100% guaranteed life outside earth.
Take my word for it.
Total hubris to believe otherwise.
Plus, I think I once heard Neil Degrasse Tyson and Joe Rogan say there is.

Given the size and age of the universe it’s impossible for life to not exist many other places.

Eukaryogenesis - Hard Steps Problem
We don't know, but advances in research seem to be narrowing it down more and more by the day, and the trend isn't that it's more likely. At least as it pertains to intelligent life. Life in general is considered to be abundant.

100%. People only think of how vast space is but forget to consider how old the universe is. So not only are there 1000000000000000000000000000000000000000 stars out there, all with the potential for life there are over 13 billions of years for life to have come and gone from any given one.

That number (10^39) is about a hundred million billion too high - give or take a factor of 100.
Still, a reasonable estimate of stars (and, given an average of one planet per star, about the same number of planets) is about 10^22. It is almost inconceivable that earth is the only place with life.
Also, the first life could not have formed immediately after the Big Bang, because the only elements then were hydrogen and helium. These two formed the first stars, and after a few hundred million years, the larger ones could have exploded, forging the other elements that are necessary for life.

I thought they estimated it was around 1 with 42 zeros after? And yes there was time when life may not have been able to form but let’s just say even 25% of the time it’s been habitable. That’s over 4 billions years. 4 billion. That’s a shit load of years in a whole lot of places that have had life.

You don't need any scientific data lulz. You'd be a fool to believe there isn't life out there.

We know for certain a planet can harbor life. And there are endless amounts of planets so you can use big brain time to figure it out on your own.

I would say it is almost certain that life exists on someplace other than earth, the Drake equation.

You mean getting reddit to do your homework. This is not research 😄
