Well being that they discovered that Jupiter sized/type planets can exists close to their star, there's probably a lot of earth type planets orbiting these Jupiters
You wouldn't need a moon in those cases.

astronomers estimate that only 1% of all Earth-like planets in the universe might actually have such a hefty companion. That would mean that planets harboring complex life might be relatively rare.
An assumption based on our circumstances.

The number of Earth-like extrasolar planets suitable for harboring advanced life could be 10 times higher than has been assumed until now, according to a new modeling study. Does this mean we have to start being sucked dry via taxation to save these planets from us for when we move there after destroying this planet as claimed?

Also true. I know that at least a few of the Jupiter sized planets orbiting sunlike stars have been found with stable orbits in the goldilocks zone.

we believe we are special. Well, okay we might actually be special in the universe but we sure hope not because we want to find other worlds we can boast to

I’m not real interested in intelligent life.
What we need is life we can eat, air we can breathe, and water we can drink.

isn’t that the truth.
depending on what we find we either go and get away from here or we send all the leftists and perverts away. lol

Lonesome in Massachussets, pardon the intrusion.
In 1993, French mathematicians Jacques Laskar and Philippe Robutel showed that Earth's large moon has a stabilizing effect on our planet's climate. Without the moon, gravitational perturbations from other planets, notably nearby Venus and massive Jupiter, would greatly disturb Earth's axial tilt
Over a very long period of time, the tugs from other planets would have a very small effect.
IOW, I very much doubt this.
When figuring out how much effect bodies have on each other, distance is more significant than mass.
The Earth's Moon is responsible for about 2/3rds of the tides.
The other third is due to the Sun.
Venus is closer than the Sun, but has a very tiny effect by comparison, which goes to show just how massive the Sun is, because, as noted above, distance is more significant than mass.
This looks like twaddle and poppycock growing out of the foolish book
Rare Earth which makes the claim that conditions on Earth produced life, and that any kind of change would mean life wouldn't have arisen -- hence, it's not likely that there's any other life in the cosmos.
Ironically, YECs sometimes saddle on
Rare Earth -- which is strictly materialist-reductionist -- as proof of their beliefs. That's just dopey.

Does this mean we have to start being sucked dry Of course! It's going to be very expensive sending spacecraft to every star, planet, moon, rock, lump of ice and wisp of gas out there. ;-)
To: LibWhacker
numerical simulations of “moon-less Earths,” which show that the consequences are less dire than is generally assumed.
ORLY?

Jupiter exerts the third biggest force on Earth, preceded by the Sun and the Moon. And it is a very poor third. Jupiter’s gravitational force on the Earth is greater than that of all the other planets combined. Simple - use Newton’s Law of Gravitation, and use relative masses and distances in Astronomical Units to keep it simple, and you will get the same scale differences.
As for Mars losing its atmosphere, I believe it was more due to the core solidifying. Loss of the core’s liquid state resulted in the loss of its magnetic field, shielding it from the solar wind. The solar wind then ablated away the atmosphere, aided by Mar’s lower gravity.

It is possible to have life, but it would not be a greate climate.
