ok here is a few simple arguments...They are flawed but also something worth thinking about
The Argument from Design
1. Nature everywhere ehibits order
2. Order requires a designer
3. Therfore, There is a designer of nature
4. The Designer of Nature is God
5. Therefore, God exists
I choose to believe the Theory of Evolution could be suitable with the belief in God
Pascal's Wager
1. The Evidence and arguments for and against God's existence are an inadequate basis for even rational belief or logical belief.
2. Yet we are forced to choose--to bet our lives--either that God exists or that God doesn't exist.
3. Thus, we must choose on grounds other than the evidence and arguments.
4. If someon bets that God exists and God exists, then that person wins everlasting happiness in heaven.
5. If someone bets that God does not exist and GOd exists, then that person will suffer for eternity in hell.
6. If someone bets that God exists and God does not exist, then that person has lost nothing.
7. If someone bets that God does not exist and God does not exist, then that person has gained nothing
8. Thus, a person has nothing to gain and everything to lose by betting that God does not exists
9. However, a person has everything to gain and nothing to lose by betting that God exists
10. Thus a person is better off Believing in God.
Also if your interested in arguments for or against the belief in God try reading books about Thomas Aquinas, and Swinburne's Theodicy
None of this is a flawless argument just rather an argument for the existence of God
