They can be produced in months! I recently held a fossilised teddy bear which had been subjected to the right natural conditions and there it was!
This photo is of a hat taken from a mine in Tasmania which had been closed for 50 years - a bit longer than the teddy but still not quite millions, eh?
Today, I visited an evolutionist's website - a blog - which dealt with this issue.
It produced anger, bile, venom, bitterness and mockery of a fossilised Ted.
Sadly, it forgot to repudiate the point with any facts whatsoever.
Difficult to see how else their point might have been made of course - the facts were rather against the writer.
