A deep thought regarding life out there

Kellicus, speaking of chemicals reacting with the atmosphere.......sounds like you just might be dealing with a methane world yourself right now..

You seem to be ignoring the fact that we were intelligent before we started using fire.

It seems to me that on a methane or hydrogen atmosphere world, an oxygen source would essentially be the "fuel" for the fire, so your cigarette lighter would contain some sort of oxygen producer to allow a flame. As to percentages of gasses in the atmosphere, remember that the largest component of our atmosphere is actually nitrogen, which is inert. On a methane world, chances are that any quantity of oxygen, or any other reactive gas would already have been "burned" into a non-reactive compound. I realize that I am using terms loosely from a pure chemistry standpoint, but you get the idea.

Current theory is that life has to evolve on a planet before it can get a substantial oxygen component in the atmosphere. Oxygen reacts with just about everything, so you need life forms to pump it into the atmosphere faster than it can all combine into other compounds. Oxygen breathing life didn't appear until the first blue-green algaes supplied the oxygen.

Intelligence - or awareness/consciousness as in "knowledge of reality" is overestimated when speaking of terrans (trying to be as objective as possible).

The terrans think that the "invention" of firemaking (rather a discovery than an invention) is something to be proud of.

On a methane world the lifeforms would probably not need to make fire and would consider it pointless.

But that doesn't mean that they would be inferior in their knowledge of reality.

I am not a Biologist or anything like that but it seems a bit narrow minded to remove the possilblity of life breathing other gases.
We understand really our own biology but have not yet found life on another world to study it. This could be because yes you do need O2 or the worlds near us just suck.

Hopefully one day we get to find out that we are not alone is this universe.
