Geologists say between 4 and 4.5 billion years. That YOU do not know has little relevance for this discussion.
Evolution is about biology, not geology. That you and your friends want to discuss geology instead of the subject of this thread shows quite well that all of you are very much aware that evolution does not have a scientific leg to stand on. It shows quite well that you and the other evolutionists here know quite well that evolution is false so you have chosen to essentially spam the thread with irrelevant information in order to distract from the emptiness of your theory.
