Aliens definitely exist, say legitimate scientists

[FrogMan]

Life is known to exist on ONE planet therefore it is 'solid' that exists elsewhere? That's not the way probability and statistics works.

100% of the planets we have explored have life so its logical to assume that at least all the planets that fit the characteristics of the one we have explored do also have life. it would likely be an incorrect assumption but it is more logical then to assume that the 1 we have explored is the exception and different from all others.

It is a mathematical certainty. Wonder what the women are like?

There's life on Mars? We've 'explored' the planets in our solar system with satellites and Mars with a probe. So far bubkis.

Dunk, don't you see that that line of thought is based on the ASSUMPTION that life simply 'happens' on a planet if certain conditions are there? Such a thing has NEVER been proven (mathematically or otherwise). Spontaneous generation however HAS been proven to not exist. We may find life one day (or it us) that isn't even carbon based and lives on a planet that our best science says is 'inconsistent with supporting life'. I believe Carl Sagan termed that "Carbon chauvinism". Or, we may in fact be unique in all of existence.

Abiogenesis is not "spontaneous generation". No one that I know of argues for "spontaneous generation".

It's entirely possible that we are utterly unique in the universe. Just highly unlikely.

We have explored Earth! we are starting our journey towards exploring other planets in our solar system but its a bit of a streach to say we have explored any of them.
