When a child reaches the age of two after having played peek-a-boo for the majority of their life and being content, they realise that just because they can't see something, it doesn't mean it is not there and it no longer makes them smile.

Does George Bush exist despite the fact that you have only seen images of him and heard a voice that may or may not be his?

Does existence depend on your sight?

Time doesn't affect matter, matter determines time. Time is a representation of movement, all matter moves. Time represents the movement of matter. The past is the concept of matter that has moved in a pattern that can now be determined and can never be changed. Present is the concept of a position that matter is in at the very moment before it moves to a position that we do not know. Future is the concept of matter being existent in and moving in a place that it has not yet reached (which is a concept that didn't exist for Africans as they did not believe in movement that may or may not come as concrete).

If matter did not exist, time could not exist. If the concept of time did not exist, that would have no affect on matter being in existence and moving continually.
