Proving God Existence

[Mister Agenda]

1) Time has the advantage over god in this.
2) God is a concept which relates the idea of a person to the idea of megalomania.
3) God too is not a thing to exist, however events and everything we know can be thought of as having been ordained by an all powerful god.

1) God existence is proved to you

If God's existence is proved to him, Whateverist is no longer an atheist. Whateverist, is this true?

2) Non-existence of God is just a refuted Concept

Asserting it doesn't make it so.

3) God will put you in hell for not worshiping him

That sounds like a very human and petty motivation for a unique being.

I think my words is too professional for common people to understand; my professors told me before that I take what I understand as a fact without explaining it enough.

An alternative explanation is that we understand you perfectly, but you're wrong.

Let me rephrase it again.
Events had a start
Relations between events also had a start
so a first event (only one) is a must
An initiator for that event must exist

The only part of your argument that isn't a premise is the second line. Even your conclusion is just another premise, since it doesn't follow from the line above it (you haven't proven that a first event must have an initiator). And while your first two lines aren't entirely without merit, they are unproven. The stipulation for only one first event rules out multiple simultaneous first events for no reason I can see except multiple first events are inconvenient to the point you want to make.
