What answer?
Do you have the evidence of the age of the earth? If so, please share it.
I have a few clues; bacteria dug up from a 250 million year old salt deposit that begin to reproduce.
65 million year old red blood corpuscles
Trunks of trees upright in coal mines
Saturns finely ordered rings..and
the chances any system could survive for a billion years just by chance. Does this help?
