The oldest near factual distance we can go back is barely 5,000 years. Carbon dating has proven itself unreliable. Sumer dating through the "pottery" method suggests an age possibly as far back as 5,000 years. And even that is not a certainty. We can tell that the earth is older than that, but we can't tell haw old beyond that. We absolutely have a lot of guesses, however. Since they are guesses, people who believe them as fact have a religion going for themselves.

Carbon dating is absolutely not unreliable whatever you say. And not only that but carbon dating is not the only method we use to date old things. It's plain stupidity to think that the world is 5k years old.
The fact that carbon dating is unreliable isn't my idea by any means. Google it.
Even tree ring and ice core samplings are judgmental in the ways they are used to date things.
We might be able to go back a little past 4,500 years or so, but beyond that, it becomes very unclear - dating pottery and written-on-clay fragments.
Lingual and genetic changes seem to trace back only to about 5,000 years. Beyond that even these kinds of datings become foggy.
What else is there other than guesswork?

FOGGY? WTF???
Carbon dating is EXTREMELY RELIABLE! Yeah go and Google it! Seems you need to:
"The reliability of the results can be improved by lengthening the testing time. For example, if counting beta decays for 250 minutes is enough to give an error of ± 80 years, with 68% confidence."
It means you have 70% to have the right date with 80 years error. So if you do it 10 times in a row, you have A FUCKING GOOD RELIABILITY!!!
And again carbon 14 datation is not at all the only one used by scientists! Do you even know how it works?
