Aliens need a lot motime to find us

Alone??? No way... Even if you subtract all the solar systems in our
galaxy with stars not conducive to life, and subtract the ones too
close to the center to allow for life, you still end up with a huge
amount of possibilities.. If you consider that it's taken us a few
million years to evolve to the point of even looking outside our own
solar system for other life.. The chances of us finding other beings
with advanced enough technology for us to be able to detect them from
this distance is very slim.. Not to mention where to look? The
vastness of just our galaxy alone is daunting.. The proverbial "Needle
in a haystack" is minuscule compared to this.. But that has nothing to
do with the overwhelming possibility of them being there... Somewhere..
