If two people who were born 6000 years ago, as in the Adam and Eve story and had two children and each two parents after that had two children and no one ever died..... how many people would be in the world today?.ie....2X2 =4...4x2=8....8x2=16...16x2=32 and so on 6000 times (years since creation) Thanks

Those are rather peculiar assumptions, but the math is straightforward: $y = 2^{6000} \implies \log_{10}(y) = 6000 * \log_{10}(2) \approx 1806 \implies$ $y = 10^{1806}.$ That is a rather large number: 1 followed by 1806 0's. Last edited by skipjack; May 30th, 2017 at 10:52 AM.

Notice as well that each pair of children in each generation contains one of each sex. Providential I'd venture. As I pointed out, the assumptions made are odd, but I am guessing that they apply only in preapple conditions. Notice that the Garden is quite commodious (as it must be to hold that number of folks).
