A theist says God is the uncaused cause (common definition) and you say you believe in the uncaused cause, BUT that's a contradiction when you say you don't believe in God (the uncaused cause). How can anyone help you when you contradict yourself?
Simple 4 Step Perfect Proof for God

1) There cannot be an eternity of the past of cause and effects in the natural realm because if there had been you would have had an eternity to be perfected, yet you still sin. Due to the exponential progression in our conscience these past six thousand years, it will not take much longer to reach sinlessness in the saved. Therefore, the uncreated created who is God of the Bible since none can compare to Christ.

2) Nothing in nature happens all by itself, not the big bang, nor a singularity, nor any supposed cycles of the universe, nor any proposed multiple dimensions. Therefore, there is only one possibility available for the cause of our existence and the universe which is the uncreated creator did it who is Christ for none can compare to the 2nd Person of the Trinity.

3) In this perfect proof, please do not waste your time by trying to disprove some god, for then you would not be trying to disprove God of the Bible as you would have thought, but some god with qualities that are not those of the Triune Godhead.

4) There cannot be an eternity of the past either of gods creating gods in the supernatural realm because we would have been derived from that past and would not still be sinning by now due to the exponential progression of conscience. Therefore, know that God did it! He is uncaused and has always existed. It's hard to get your mind around that fact, but we are not meant to understand it, only accept it as the logical conclusion to the evidence for our faith.

Tarry no longer to receive the gift of eternal life.
