Please learn biblical exegesis, the bible is quite unclear on the age, go learn the 6000 year formula was done by a Catholic priest relatively recently.
@BritishFailedAesthetic Seder Olam predates Bishop Usher by a few hundred years. His math was relatively close (current year is 5784 based on Seder Olam), the mistake is assuming the 6000 years is the actual age of the Earth and not just the total years from a relatively random starting point.
@BritishFailedAesthetic I can see that, it doesn't say for sure. I just have met a lot of Bible believing Christians who swear up and down the world is only around 6000 years old. But a lot of them also don't believe in space so that's saying something lol
