do you think aliens are real?

Because, even assuming evolution, the odds of sentient life are slim to none. It's unlikely enough to find mere bacteria anywhere near us, let alone intelligent life.

But how can you know that in the infinite universe there is not another environment similar to/the same as earth?

It happened at least 3 times just on this planet so I think the odds are good that it can happen on others.

In the grand sweep of universal time I think it highly likely that life has evolved elsewhere somewhere and some when else. Its is just not likely at all that it would exist at the same time as we do. And really, intelligent? Just how intelligent do we presume ourselves to be?? What are the odds that other "intelligent" life forms have destroyed themselves as we have come so close to doing so often?

In the first place, earth is in the most strategic place possible to support life, for another thing it is incredible that the elements on this earth are perfectly balanced for us and other organaisms to survive and thrive.
For example, our air is actually a mixture of gases, nitrogen (78%), oxygen (21%), carbon dioxide (0.03%), and argon (0.09%). Hundreds of other gases make up the other 0.07 percent. This mixture of gases is perfect for supporting all kinds of life, for if any of the gases were in smaller or larger amounts earth would quickly become dangerous for life to be on.
This is only one of the thousands of examples that show that life on other planets other than our own is practically out of the question.

We're clearly intelligent enough to harness the power of the atom, control fire, fly higher than the mightiest bird, tame the most powerful animals on the planet, dive deeper than almost any fish, communicate around the world in seconds, divert entire rivers, build machines to work for us, kill any land animal with the twitch of a finger, and travel into space. Despite our faults, I'd say we're pretty freaking intelligent.

@Rebel - 3 times? First time I've ever heard that one. Even working from an assumption of the possibility of spontaneous generation, how on Earth does one arrive at 3 times?

@Everyone - notice I am NOT saying "impossible." I am saying "unlikely." Something that is unlikely is infinitely more likely than something that is impossible. I am simply saying, even operating from an assumption of spontaneous generation, the odds of intelligent life close enough to us to be of any importance is really, really low. At any rate, we certainly shouldn't be wasting billions upon billions of tax dollars on attempting to find hypothetical alien civilization that is several dozen light years away at the very least.​

I agree!!

Isn't it somewhat presumptuous to asume that other organisms would necessarily have exactly the same 'life' requirements as those on earth?
