Like terminator right

haha but seriously.
why carbon based, just because we are carbon based?
why is water necessary for life. it may be for life as we know it and define it in our limited knowledge, but elsewhere it may be rocks.

@Cheegum

Because our petty human imagination can only perceive others in our own image. Like Stephen Hawking who can be excused for assuming that every life form out there is resource greedy like white man.

you got it brotha

@TLK

Metallic life form may not exists because of the physical properties of metal, but I think scientists do believe in the possibility of Silica based life form.

but what do we know about life aside from how we define it? there can be different life forms that operate on very different principles, they may be based on elements we know, or on elements that dont even exist on our planet.
