This is false logic.
Most religions have a coherent creation myth. The Judeo-Christian-Islamic faith states that God existed before everything else and was not created.
This is an axiom of faith that can be accepted or rejected. Your statement is false logic that is rejected by Jews, Christians and Muslims and irrelevant to non-believers.
If our complex universe for being in such complexity requires a complex creator as god then that god should also require a much more complex creator too....this argument goes on and on therefore it is wrong. Conclusion = its obvious that all religions are man made and false. To be good (if that is our intention) we don't need BS. Man can create a perfect world with his own mind. Man can think and find good and bad on his ownself. Religion was made up in times when there was no communication on the world and when there was a lot of chaos with man being totally helpless. Actually the chaos today is perhaps the same as those times but we have the advantage to see and communicate better. Any suggestions with good proofs and reason ?
