I totally get what you're saying, but without trying to be too speculative why does the assumption seem to be that only an earth like planet could
sustain intelligent life?
Thinking logically, it would make sense that another earth like planet could possibly have evolved a species that is somewhat characteristically
similar to us. But that, to me, does not preclude a totally "alien" (to us) species evolving under a different set of atmospheric and geologic
conditions. There may not be complex life on Venus, Mars, and Titan because complex life still seems to be a relatively rare phenomenon. I would
venture a guess that few, if any solar systems contain more than one intelligent species.
My ultimate point is that if I were in a position to be scanning for planets and predicting where to look for life, I wouldn't narrow my search
solely to earth like planets. Really, any planet with an atmosphere could potentially harbor life.
And just so my beliefs are out there, I fully believe that our universe is teeming with life. I see no reason to subscribe to the rare earth
hypothesis or any such skeptical view on extra terrestrial life.
The universe is such an enormous place, unfathomably so, that there may only be primitive life or pre electronic intelligent life in our neighboring
Who knows? I know it's a movie, but the Na'Vi in Avatar are a good example of intelligent life that may exist that we'd likely never know about
unless observed directly. It seems foolish to assume every intelligent species will have progressed as far as us or well beyond our capability.
It seems much more likely that at any given time, there are tons of primitive intelligent species, some that do not make it beyond our current level
of technology due to the cataclysmic nature of the universe (impact events, climate shifts, etc), with only a select few possibly lasting hundreds of
thousands to millions of years. And at that point, it would make sense that the species goes totally stellar and leaves terrestrial planets in favor
of massive spaceships containing the entirety of their species.
The volatility of starsystems and even planets, to me, suggests that an ultra intelligent (very evolved) species would reside in space, not on a
I could be way off, but these are just my (scattered and somewhat random) thoughts on E.T.
