Since you assume 13.7 billion years ago, the obvious question is: how do you, or any other person know?
If you were to research carbon dating (C-14), you will find that there are a lot more problems than what is being packaged and sold as an exact science. For instance, there are at least three (3) assumptions made in using C-14, and any other radiometric dating method. Do you know them?
"If a C-14 date supports our theories, we put it in the main text. If it does not entirely contradict them, we put it in a footnote. And if it is completely 'out of date," we just drop it."
T. Save-Soderbergh and I.U. Olsson (Institute of Egyptology and Institute of Uppsala, Sweden)
Even the C-14 apologists admittedly play a shell game. So why are we in such a hurry to fully accept their conclusions? The global warming myth didn't work either. 1 Th 5:21
Obviously you have no idea what you're talking about. Carbon-14 dating is used to date old pottery, not the age of the earth let alone the universe.
The age of the universe has been determined by three different independent techniques, all of which yield the same age.
