What method can we use to identify the true God ,or Gods, among the many religions in existence?

I had the same problem so I solved the problem by disowning all religions and accepting God alone. Yes I believe in God (Supreme being) alone. Religion is for money, greed, and power. Religious things always ask for money and to donate generously, they are power hungry because the highest number of followers will rule and because of that all the wars have been due to religion and finally all the priests and them are greedy for money and power. So religion is just a Company that promises to sell God and rip you out of money so I just pray directly to him in my mind and talk to him openly.
