I believe in aliens, do you?

Sure.  The universe is a big place. I mean, they might not be an advanced civilization like us, maybe just simple prokaryotes

I agree with you, the universe is too big for only us to exist as Earth makes up such a tiny portion of it as a whole. There has to be more life out there.

There's something called the Drake equation that tries to calculate the odds of other life in the universe, but I don't remember all the values.

Oh wow, really? I had not heard of that. There are all sorts of theories out there in favor and against the idea of extraterrestrial life. It can be a very controversial topic.

It's almost a paradox.  Like the Drake equation calculates a lot of other civilizations, yet there is no evidence of the existence of any.

That sure is interesting, I'm going to have to research more into that.
