I believe there is life out there can't believe ours is the only planet that has life

Same here, never could understand how people might not. Infinite diversity in infinite combination seems to be the underlining harmony of the Universe.

To me it doesn't make sense, the vast amount of planets and 1 occupied. Not a chance

I don't, or at least I'm very skeptical. We don't even have a good idea of how biogenisis can occur. The first self-replicating molecule sets in stone the evolution domino, but how such an incredible molecule can come about is elusive. Fermi's paradox should be an issue for you too.

You are absolutely correct on how we have no "good" idea of how biogeneis can occur. Me and Fermi are cool with each other...great physist, lowsy poker player (still owes me $50).
With infinite diversity in infinite combination I believe in favor of life and habitable planets. "Wether that life is intelligent and we will be able to recognize it is another debate.
But with the sheer scope of matter drifting through space, I'm more inclined to believe that a planet could replicate the same conditions in different parts of the Universe.

I mean, it's not actually infinite though, neither in combination or in observable space. There are very particualar conditions required for life, and as time goes on and we approach heat death other instances of life coming about become less and less feasible.

We barely even made it ourselves. The ice ages nearly wiped everything out, and there was a time before animals where the plants nearly choked on the hyperoxygenated ready-to-burst-into-flames-any-second atmosphere, and the animals came around to respire just in time.

There are a profoundly large number of variables required for life, and I think the number is probably higher than people think. So I think it's very unlikely there have been many, if any, other living species in the universe. Moreover, if any have ever existed, I would wager they'd have killed themselves off by now. I mean, we're not doing spectacularly ourselves, I doubt we'll last over 10,000 more years. There's a very small window in which life exists, and if life is as rare as it seems, it's even more unlikely there'd be an overlap between two species in the 4 billion years or so they have to live on different ends of the universe, and even more unlikely again that one of the species in the overlap would be one on earth, and more unlikely still it would be us humans.

Looks like we're gonna have to disagree on this one then and still search for the truth. There is so much we haven't discovered or taken into account into our calculations on the matter.
I'll sign off here with a video.....thanks for bringing up good points to discuss on the subject.
