For the sake of argument, let's assume that the following statements are true:
Everything that had a beginning had a cause
The universe had a beginning.
Therefore, the universe had a cause.
We call this cause God.
Can someone explain to me how you can take such a deist concept of God and then prove that this is in fact the God of Moses and Abraham? I fail to see how anyone can make that leap. The evidence linking the deist creator to the Hebrew deity is just too thin. How do you know for sure that it is in fact the Hebrew God Yaweh that created the Universe? Why not Brahma? Or Ahura Mazda? Or the vomiting Mbombo? Or Mangala?
Buddhists don't believe that the universe had a beginning. "Conjecture about [the origin, etc., of] the world is an unconjecturable that is not to be conjectured about, that would bring madness & vexation to anyone who conjectured about it."
