Absence of evidence is not evidence of absence.
That is a given.
But if there were some form of life outside the Earth, it would be ubiquitous and easily identifiable and practically in every direction we could look.
So far we have found none even though we have spent astronomical amounts of treasure in the search for it........
“ But if there were some form of life outside the Earth, it would be ubiquitous and easily identifiable and practically in every direction we could look.”
Not even close.
What are you talking about? How could we prove or disprove life in the universe when we can still only really see huge gas giant planets that occlude their son.
You are operating under the fear that somehow you become smaller and less important the larger and more incredible our universe gets as science advances.
Let us talk about the “search”.
SETI is looking for radio signals.
I call SETI the Search for Extraterrestrial Idiots.
No advanced civilization is going to send out radio signals in the open so that any other star faring civilization could identify their location and attack at will.
That is an insane strategy.
Only homo sapiens are dumb enough to do that.
