CS: it doesn't matter, one of that matters because any answer that comes that less than 4.54 billion years for the earth and 13.77 (thought it was 13.72?) billion years for the universe is wrong. And to tackle that would be, as mentioned above, to prove general relativity, special relativity, optics, biology, physics, chemistry, astronomy, statistics, mathematics and a number of various other branches of science wrong.
Even the Mormons know not to do that.
