You are assuming a day to God is the same as a day to us. Can't be. Second you are assuming carbon dating is accurate and we have no way of knowing how accurate it is. Once we go pre-history our estimations are a guess.
And I understand that carbon dating might not be 100% accurate
But we're not talking about a discrepancy of a few years, or even a few hundreds of years
We are talking about a BIG ass gap of millions of years difference
Where paleontologists & other scientists that say Dinosaurs were around 100 million years ago
Where geologists & other scientists that say a huge asteroid hit us 60 million years ago.....in which the crater is still there
Where astronomers, meteoriticists & other scientists who've studied fragments of meteors/comets from other planets
That say some of these fragments date back hundreds of thousands if not millions of years ago
Fam thats a HUGE discrepancy in time between what everyone else is saying compared to what religion says
And its hard to just make the excuse "oh well carbon dating might be a little bit off"
Its like going to Chernobyl to measure the radiation levels embedded in the earth & saying
"Welp this incident happened either in the 1980's or about 50 million years ago"
Wait what the hell?
You can't be that far off in the carbon dating analysis 
Because at that point, it means you're just guessing & randomly picking numbers from a hat, LOL
