Our current knowledge points to the first planets appearing around one billion years after the big bang (heavy elements need to be bred in stars in sufficient quantities first and be ejected in super novae), and evolution taking another billion years to produce eucaryotic life, then another three billion for plants to form. So while obviously we can't say for sure, I stand by my original statement when speaking in terms of orders of magnitudes. I think it's a sensible argument. |
