Think of the variables, gravity, temperature, comets/cosmic collisions, and 100's of other things that could have drastically changed evolution of intelligent life.

Furthermore, we don't exactly know the threshold for life and how and where it evolves. We assume there needs to be water, so there's already a big similarity between our environment and a possible alien one. But it could be that the window for environments that sustain higher life is relatively narrow, therefore making it even more likely that any life that did exist, would evolve in a similar manner to us.

Well thats definitely a point being debated, extremophiles can exist in extreme heat/cold and in very toxic enviornments. Question is on such a harsh planet could anything evolve beyond the very simple structure we find on earth of these extremeophiles.

Not saying it wouldn't or couldn't happen the way you said, just that I don't think it's so unbelievable they might not be humanoid or partially humanoid in nature. We don't really know anything about evolution of life on other planets, or even enough about life, to really hazard an accurate guess.

We can take some queues from our own evolution and that of our planets micro organisms and fauna. We have some idea of what certain conditions would favor in terms of evolution, temperatures, etc..

With the vast size of the universe its very possible if there is plentiful life all around it that there are somewhat similar beings to us, but likely they will have very few things in common with us other than intelligence.

I don't discount any of those possibilities, I just in the frame of this debate am talking about the obvious coincidence the aliens people describe seeing are all very human like and I think most people who are skeptical agree that's a sure sign of them being false claims.

All that said, I have come to believe for quite sometime we have never been visited by aliens if there are even any out there. The more you research the cases, the more they seem fishy. Also there are strong logical arguments against us being visited, but not being 'contacted' as a species. It's more likely, we're not visited at all. Beings that could bend time and space, as they would have to to get to us, would have much better things to do then spy on us from afar, and experiment with us and our cows.

I agree, and yeah I don't buy the idea they would not contact us if they came all this way, nor would Roswell be likely considering IF aliens could come all this way using such amazing technology to do it, I doubt they'd then crash into our planet.
