@farmerman,
Why do you think 'panspermia' requires alien intervention?
You would have an idea if the info was available to you.
And science couldn't confirm the existence of nanoparticles until the electron-microscope was developed.
Where is your 'counter-evidence'?
tepe is 11,600 yrs old, pyramids are 10,000 yrs old - History is manufactured to lead you to the trough for your pigswill.
You figured out the 'measurement-problem'? No. Because it requires lateral thought.
Please.
