You're not making any sense, JJ.
how can you say it doesnt matter at all?
Because it doesn't. And you'd only think that was weird if you didn't know what radioactivity was. Which you clearly don't.
some say at the beginning stages of Earths creation, there were NO atmosphere for a while
Yes. And there was
nothing alive at that period in the Earth's history, because it was before the evolution of living things.
There are no fossils from a time when the Earth had no atmosphere, because life could not exist under those circumstances. If that had ever happened in Earth's past after the evolution of life, the Earth would be lifeless, today. (And it's not.)
if you were to fall in a volcano and millions of years later your bones be exposed to people, you think they woudlnt know at all that you were burned?
That's not how fossilization works. If you were to fall into a volcano, there wouldn't be any bones to find.
i thought that the c-14 dating actually has that carbon CLOCK running after the thing dies, so basically it IS amount really.
No, it's proportion. Maybe you should look up how radioactive decay works? It proceeds in a geometric progression, which we measure as a "half-life." (You've heard that term before, right?)
depending on the atmosphere and where he died, he coulda had a c-14 disease in his body that could have depleted the c-14 in his body before he died THUS giving it a LARGER age than its suppose to have...
There's no such thing. Seriously, there isn't.
now lets say this thing died because of that, are you to say WE as scientists wouldnt know this?
No, we'd know. But it wouldn't have any effect on radiometric dating.
decay of isotopes means the amount that is given off?
No, that's not what it means. It means "the proportion of the isotope to its decay product." It's about proportion.
