RE: Why haven't we found aliens yet?

in #life7 years ago

I think you leeft out the most probable. The universe is huge (in terms of time and of space) and space travel is slow (as far as we understand lightspeed is the limit) and complex. The chances of two or more species evolving around the same time period, achieving interstellar space travel and being close enough to actually meet... may be statistically very, very, very, very, very, very, very, very, unlikely.

Sort:  

Yes that might be one of the reasons why we haven't encountered any alien life but any such intelligent life must be able to find the evidence of another life capable of interstellar travel even if they're not present at the same time, don't you think? I mean there must be a lot of data and information created by intelligent life in the universe. Voyager 1 and 2 come to mind.
But yeah as you said, that is statistically very unlikely.
