Question: If there was another planet with the same conditions as earth could there be simular life forms to humans?

Yes I think so, because we could have evolves from so many different life forms on earth, we could have been swimmers or had wings, but somehow, a 2 legged upright species with thumbs won over everything else. So if there was a planet like earth, I think it is pretty likely that they would be upright and 2 legged since similar evolution would probably take place!
