Perry, the only beginnings you have experience with are beginnings within time and space. You have no experience with beginnings outside of time and space. So I'm not sure that it's logical to assume that beginnings outside of time and space require a cause the same as beginnings within time and space.
Island Man,
I am not suggesting that the Cause of the universe had a beginning of any kind. It would by necessity, be an uncaused Cause. Why? Just connect the dots.
We can clearly ascertain that the universe had a beginning. Everything in our universe had a cause. The cause of the universe must be uncaused, otherwise its own cause would preceed it, placing it back in the space time universe which is impossible, if it caused it in the first place. See what I mean? Pretty simple logic.
Some of the folks here are just having a hard time imagining an existence of any kind without time. I suspect because it is a direct negation of Materialism which has been adopted by some who leave the watchtower. The human mind abhors a vacuum.
This argument (not to mention the science behind it) demonstrates the failure of Materialism to explain our existence.
