Aliens DO exist – they just haven't visited Earth, NASA veteran claims

Aliens exist — they just haven’t visited Earth, a NASA veteran has claimed.

Dr. Gentry Lee has worked at the US space agency since 1968, when he first got involved with the Viking mission to Mars. He has since spent more than half a century designing probes to land on distant planets — but argues Earth has not yet been visited by otherworldly beings.

“There exists nothing today that says any alien or any alien machine has ever landed on the planet Earth,” he told the American Association for the Advancement of Science (AAAS) conference in Phoenix. “If you believe otherwise, you are being misled.”

According to the expert, in every case of a supposed UFO sighting or alien encounter, there is likely a simpler explanation for those phenomena. But when it comes to distant planets, life has “just got to be there somewhere”. …

I believe there are several species of known Aliens. Our government and military have continued to presume Americans are “still not ready” to officially make such an admission.
I have no doubt the proof has long been available to the military. Oh well. Stay alert for more “Weather Balloon” sitings. This has not changed my belief in God and the power of His guidance.

The Bible shows that there is intelligent life elsewhere.
It just hasn't 'fallen', like man, here on erf.

Heb 1:2
Hath in these last days spoken unto us by his Son, whom he hath appointed heir of all things, by whom also he made the worlds;

Heb 11:3
Through faith we understand that the worlds were framed by the word of God, so that things which are seen were not made of things which do appear.

Worlds, plural, more than one. Then:

Isa 45:18
For thus saith the LORD that created the heavens; God himself that formed the earth and made it; he hath established it, he created it not in vain, he formed it to be inhabited: I am the LORD; and there is none else.

I don’t think He created the other worlds in vain either – he formed them to be inhabited as well.

Ephesians 3:9
And to make all men see what is the fellowship of the mystery, which from the beginning of the world hath been hid in God, who created all things by Jesus Christ: Ephesians 3:10
His intent was that now, through the church, the manifold wisdom of God should be made known to the rulers and authorities in the heavenly realms, Ephesians 6:12:
"For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places."
Job 38:7
When the morning stars sang together, and all the sons of God shouted for joy?

[Revel]

If anyone ever actually confirms the existence of Aliens on earth then it would prove one thing for sure. There would have to be methods of travel that involve physics other than traveling faster than the speed of light. Since we already know that one cannot even reach the speed of light. And in order for Aliens to reach us they would have to travel in a fashion that was equivalent to traveling much faster than the speed of light.

Well, Isaiah 45:18 says that God “formed it to be inhabited”; the “it” would not just be the earth but the entire universe, if the verse is read in its entirety.

[nickcarraway]

They haven’t checked home depot?

[A_perfect_lady]

They probably lock their doors as they fly by.

[SaxxonWoods]

Nice comment and very true!

Also, we may be the only “nearby” technologically advanced civilization, and we will be seeding the rest of our area when we are capable.

“Aliens, ETS, etc, do not exist, have never existed and therefore have never been here.”

Are we required to believe you? Can you prove aliens don’t exist, despite thousands of years of witnesses to the fact. Or did you just pull that out of your ass?

[Olog-hai]

Reliable witnesses?

Plenty of “witnesses” to the existence of the pagan gods too.

[Verginius Rufus]

What you have as "the worlds" in Heb. 11.3 is tous aio:nas [o: standing for omega] and saecula in the Latin translation. Both the Greek and the Latin terms refer to periods of time (of various lengths--a generation, a century, an indefinite long period, etc). I don't see how that becomes other planets.

But when it comes to distant planets, life has ‘just got to be there somewhere’.

He added: ‘We are going to find life of some kind somewhere else. The odds are overwhelming.’

That is an article of faith. We do not know enough to calculate the odds. We may well be alone in the Universe, or at least any part of the universe we can observe.

Of course, finding “life of some kind” is a far, far cry from finding alien civilizations, or even “intelligent” aliens.

[citizen]

aliens are likely to exist somewhere

Also, "some when." It's not just distance. They don't have to exist now.

Fantastic civilizations could have risen, fallen and become lost in the vastness of time.

But when it comes to distant planets, life has “just got to be there somewhere.

Wonder why nobody wonders if we are them and got stuck here.

Lenny didn’t bring extra fuel rods?.

[PhiloBedo]

I’m guessing he’s never read the book of Ezekiel.

[DennisR]

This guy is clueless. Aliens HAVE visited earth and look exactly like humans. In fact, it is almost impossible to tell that they are aliens. Another name for them is “Democrats.”

[dagunk]

Aliens from space lock their doors when they go through our solar system.

[Az Joe]

Name one witness

[MayflowerMadam]

Maybe they exist; maybe they don’t. There’s no reason God couldn’t have, or wouldn’t have, created other beings elsewhere.

I’m not gonna worry about it, though.

[chud]

Obammy Says They Do exist aswell...

And then President Trump said that Obama had revealed classified information.
Interesting. What do they know?
