Nobody knows whether or not there is a "God". People have yet to come back from the dead to report findings either. It's all philosophy.
So because you don't know something, no one else does? Seems like a pretty arrogant position to be taken.
God is there. I know that from personal experience. He loves you too.
It's amazing how God has made it clear that He will reveal Himself to those who have faith and He does, yet there are so many people who never test it. They just declare him unknowable.
"If any you lack wisdom, let him ask of God who gives to all men liberally and upbraideth not, and it shall be given unto him" (James 1:5).
"Ask, and you shall recieve, seek and you shall find, knock and it shall be given unto you" (Matthew 7:7).
"If any man will do his will, he shall know of the doctrine, whether it be of God, or whether I speak of myself." (John 7:17)
"And Jesus answered and said unto him, Blessed art thou, Simon Bar-jona:
for flesh and blood hath not revealed it unto thee, but my Father which is in heaven" (Matthew 16:17)
"And this is life eternal, that they might know thee the only true God, and Jesus Christ, whom thou hast sent." (John 7:3)
We cannot be recieve Eternal Life without knowing God. We cannot be saved in ignorance. How can we know a Master we do not serve? The best way to serve God is by serving others.
Study the doctrine. Experiment on the Word and Ask God and He will reveal Himself to you. And once you learn that, your whole world will change.
