The aliens are silent because they’re dead

These kinds of fantasies are familiar to those who know all too well the absence of critical thought that exists in such “biological sciences” as evolution.  Instead of accepting facts that are so startlingly obvious, denial and obfuscation mixed with a bit of creative license forms a theory that “solves the problem.”  The thought process takes place like this:

Life is here.  How did it get here? It evolved.   Any questions?

There is no life beyond earth.  When all evolution needs is water, why is this so?  Life is not out there right now but it did exist in the past but went extinct.  Any questions?


Neither of these ideas is a solution. Neither are scientific.  Both ignore reality.  Both depend heavily on ignorance as much as imagination and neither actually satisfy a thinking person.  Amazingly, both are based upon the absence of evidence.   I don’t believe one needs to be a critical thinker to exclude from possibility two theories based upon the absence of data.  But hey, that’s just me.
