5 proofs I know that God exist:
1. The air I breath
2. The reason why I am still alive right now.
3. The reason why earth is still running on its right orbit.
4. The reason why Armageddon and apocalypse has not arrived yet
5. The blessing you I received everyday
If you don't received these 5 things, then you should start praying and ask for forgiveness.
Make your self closer to God because if you don't, the one opposite to God is the one who is with you probably.
There maybe no scientific proof that God exist. But remember this, It doesn't mean that because you don't see it, its means that it's not there...

God moves is MYSTERIOUS ways....
