First of all I haven't ruled out a creator.<quoted text> Lets apply Hawking argument against God.
Causes must precede their effect in time (Except gravity)
There is no time prior to the beginning of time
Therefore the universe cannot have a cause.
If that rules out God then it must also rule out gravity. Atheists rule out God but do not rule out gravity.
But lets examine this, Can you find gravity now?
Can you find or show evidence of a creator>??
We can find gravity, we can also understand what general relativity
mean to gravity and the space/time continuum.
We can identify how gravity can slow time and contract space into a singularity. These are measurable things, now show me the effects of your creator. Causality only makes sense to things bound in time. We know there are things not bound to time as we are, such as quantum effects and gravity. These effects are demonstrable and testable. Demonstrate the effects a creator has on time and gravity in our world in a testable and measurable way. showing on paper what it is. Then you have an argument, but as it is you have only a belief and no measurement or observation.
