The statement you make draws it's conclusion from...what?

The fact that the entire "chances of" rationale fundamentally misstates the problem. How many chances you have of obtaining a certain outcome are largely irrelevant apart from correctly evaluating the events required for that outcome to take place.

In a very real sense, the whole line of reasoning is predicated on "the gambler's fallacy." ....hence my reference to Michael Crichton and his famous speech on the Drake Equation before SETI.

When you are talking trillions, or more, then there are likely hundreds, if not thousands of planets with life.

I think it is hubris to believe Earth is the only planet with life, even intelligent life.

I also think an omniscient God has more “capacity” than just one planet & one species in a vast universe.

It all those. “Relatives” of ours are so nearby, why haven’t they looked us up.....or at least dropped us a card? I’m offended!

Agreed.

O tell of God’s might, O sing of His grace, ...

I have long held that the loss of "God's NIGHT" to modern light pollution has materially diminished our wonder of our small place in the cosmos. For most of us moderns we have to make a special effort to see a truly dark night sky. Pre-1900, our ancestors would see it almost every night. I feel that it does make a difference!

Considering the fact that there are something like 200 known moon in our solar system alone, I’d guess that there are many more moon than planets in the universe and that’s a lot.

I also think our earth, moon pair is really more of a dual planet system due to their relative sizes.

Thanks onedoug, for referencing “The Privileged Planet.” IIIFFFF God has already peopled other worlds, He will tell us all about it/them in His own good time. WE were created in His image, and the Scriptures tell us indirectly that we will spend eternity developing the universe; therefore, I have doubts about life on other planets....as get! That will happen AFTER Good finishes settling the sin question on Earth, when satan had been cast into the lake of fire and the New Jerusalem had been brought down from Heaven and takes its place on the New Earth. It is not arrogance or hubris to think we are unique when The Creator SAYS we are!

Life grows and thrives in the coldest and hottest places imaginable. Survives on nuclear fuel rods, the deepest deeps of the oceans, in lava, and blocks of ice for thousands of years.

The earth is merely a spec of dust in a universe beyond measure and age. Our civilization’s lifespan is not even the quickest flicker of light when compared to the age of the planet (1/15,000 of second if the lifespan of the earth is an hour old), much less the universe. Applying this time span to the universe, comparably we have been aware less than 1/60,000 of a second.

Sure, but Drake’s equation is just a Fermi estimate - a reasonable guess about a matter we don’t have nearly enough data about. There’s no doubt the press sensationalizes such mind-exercises and the speculations some scientists attach to them, but the fact is that we do know that intelligent life is allowed by the physics of this universe. Speculation about how often it occurs is certainly more legitimate than speculation about how common water flowing uphill on other worlds might be.

So what in the universe isn't? Its sum is the total of its parts. And for our part at least, it's as if the universe has created eyes and mind to discern itself. Thus we can, in that sense, speak with some confidence of its measure and its age.

"Reasonable" in what sense?

... but the fact is that we do know that intelligent life is allowed by the physics of this universe. Speculation about how often it occurs is certainly more legitimate than speculation about how common water flowing uphill on other worlds might be.

I don't see how until you've repeatably demonstrated how it in fact started here.

Life, any life, is a proverbial "turtle on a fence post."

We know the capabilities of turtles, and we know the characteristics of fence posts. All the calculations in the world are not goring to give you a legitimate probability for how often you can expect to find another turtle on another fence post.

Thank you. I love “The Privileged Planet”.

Though doesn’t it seem odd to you that despite an abundance of evidence for God in the universe, there is absolutely none at all for Satan outside the human mind? And wouldn’t that undermine monotheism?

Another goodie - to my mind at least...Gerald L Schroeder: “The Science Of God: The Convergence Of Scientific And Biblical Wisdom”

God said that mankind will rule His creation (all the created universe) and He sent His Son in the likeness of sinful flesh to redeem mankind. It's logical to say that if there is life out there they are in need of a savior too and that savior is human.

“.....there is absolutely none at all for Satan outside the human mind?”

Whaaaaaat? No, I guess there isn’t, if you discount an insignificant minor little item called the BIBLE!

No offense, but I’m sorry I replied to you. You appear to be so far out in left field that I can just barely pick you out with my 60X spotting scope.

"Reasonable" in what sense?

In that these inferences don't violate or contradict any known facts and can be considered a valid possible consequence of those facts. Fermi estimates are often required in interviews in the software industry - it's a good way to find out how candidates approach and reduce problems. Without data, the results can't be confirmed of course, but the guess-timates often turn out to be quite good.

Life, any life, is a proverbial "turtle on a fence post."

So was the notion of stars having planets. Prior to verification over the last couple of decades, we had no way of knowing whether planets actually existed anywhere but here around our star. But what we could observe of our own star certainly warranted speculation. Detecting life will be far harder, but speculations about it's existence don't rank with speculations about physical impossibilities, IMHO.

Sure they do. Furthermore, such inferences camouflage the fact conventional "science" threw in the towel on abiogenesis a long time ago.

What's more if you can't confirm your guesstimates, what makes you so sure Fermi estimates are any better than the guy looking for his wallet under the street lamp, because the area he lost it in was dark?

Finally, unconfirmed, as opposed to disputed, planets are nowhere near analogous to attempts to make "life" just another mundane physical process.

Showing me a bird on a fence post does zero to explain the turtle, even if it's the exact same fence post.

The sad fact is this area of science is tainted in the same way as "gun control" advocacy; forget whether the thesis is verified, plausible is good enough....just assume it's correct and legislate accordingly.

Be sorry as you may, but there is none in Torah outside what I believe to be God himself.

And, as evinced in Isaiah 45:7: “I form the light, and create darkness: I make peace, and create evil: I the LORD do all these things.”

What legislation? SETI and similar projects have received some government funding but also plenty of private financing. Mind-exercises like the Drake equation are just intended to provide some initial framework for research and discovery - they don't deserve the uncomprehending awe the press always bestows on things like equations, but they do serve a legitimate purpose. Without such things we'd never have bothered looking for or finding extra-solar planets.

It was in keeping with the analogy. There's no actual legislation involved unless you count educational standards.

I disagree.

The fact that we knew planets existed makes it impossible to claim we'd never have looked for them elsewhere: just as we will look for life elsewhere.

But again, that is irrelevant. Looking for planets is nowhere near assigning probabilities for finding them...particularly when you've already admitted you have no idea what circumstances repeatably cause planets to form.
