There are 100 billion galaxies in the universe

https://www.space.com/25303-how-many-galaxies-are-in-the-universe.html

Wouldn't it be surprising if Earth is the only one of those with intelligent life?

Just wrap your head around this... there are more planets in the universe than there are atoms in the universe.

It's likely more like 200-400 billion with 11 billion Earth like planets. And no, there's about 2 trillion galaxies. 180 billion is the old estimate.

No. My book said that this is all she wrote and thats final. Those other planets and galaxies are just Gods way of giving us pretty lights at night and he has an insane amount of OCD so he placed them just so.

I think the study isn't fully concluded, which is why 200 billion is the best estimate for now.

Why? With a survey size of one and an unknown total number of planets in the universe, we have no way of knowing how likely or unlikely extraterrestrial life is.
