Learning the truth about the age of Earth was and is a process , just like learning anything. If you want to know how the process in discovering the age of Earth went then this is the best way here.<quoted text>
The problem is with your "plucked out of the air' aging process, that if you have several scientist separately carefully observe and test, they ALL come up with DIFFERENT DATES.
(hint: they're making this s*** up as they go)
Science is a process, one that progresses with new discovery and we haven't discovered everything about this planet yet , but have a vast amount of knowledge that has accumulated over the years by the progression of science.
We now have the ability to expand our knowledge about the universe, but are barely more than fledglings when it comes to that. But as far as the Earth you can learn what the scientists before leaned and how here if you really want to know.
I have my doubts you want to do anything but argue though.
