I don't mind being a few million or a billion years out either way but even as a ball park number it will do for me.
If you could actually produce evidence of a specifically young earth like science produces evidence of an old earth, instead of personal theory, possibilities and supposition, then that would be much more convincing and interesting to me.
The only evidence science has for an earth in the 4.5 billion year range is radiometric dating. What evidence is there for a less than one million year earth or for any exact age? There are a few possibilities. How long does it take a mountain range to form? How long does it take to wear one down? If you go by how long it takes to build one at today's rates, the earth is very old indeed, but I'm not sure you could make it to the 4.5 billion year mark that way.
If you go by measured rates of sedimentation, the earth is much younger than that figure. I don't have the figures but there is a guy who claims to have them. From what he said, the rates of sedimentation for equal periods of time from the archean to the holocene, show slower and slower rates of sedimentation going from the oldest units to the youngest units.
This evidence here would show that the measured ages are inflated and that inflation grows larger the further you go back in time.
What age would I give to the earth? I can't see any reason other than radiometric dating for it to be any older than a million years.
