For different religions there are God, Gods, Goddess or Goddesses . . . and then combinations of both! Hindus believe in hundreds of gods and goddesses. Before Judism and Christianity, many religions believed in female deities only.
It just depends on the religion. Everyone has a right to believe what they want to believe - or not to believe. :)
There is no evidence to suggest that a god or gods exist in any way outside of the believers head. Everyone is an atheist to all the gods that mankind has ever believed in, some people just go one god further. They are a primitive attempt to understand the world.
I believe in God just as much as I believe in gravity. I recommend you Start here http://web.mnstate.edu/gracyk/courses/web%20publishing/aquinasFiveWays_ArgumentAnalysis.htm And here http://en.m.wikipedia.org/wiki/Teleological_argument#_ Just remember these are starting points. As you study you will find arguments, counter arguments, and counter arguments for the counter arguments. Ultimately, there is an element of faith. But faith is not a bad thing, nor is it limited to religion. Faith encompasses all aspects of human life. Even in science we do not accept absolutes. So, it is normal to get discouraged during our studies, and question ourselves. It is at these times we must remember all of our findings, and how the Lord has blessed us with our own miracles in our lives. I recommend speaking with a religious leader you trust, especially if he/she is a theologian. God bless and happy studying. :)
For God so loved the world that He gave His only begotten Son that whosoever believes in Him should not perish but have everlasting life. John 3:16. Yes, there is a God. He loves you and wants to be your friend.
Why not ask Him directly if he exists? Spend some serious time in pray and contemplation, asking to feel his spirit. If you get a response you will have a personal testimony no one can take away from you. Asking other people will only give you the opinions of those people, and you will hear both yes and no. Seek your own relationship. I did, and I now have my answer. I am no longer swayed by the opinions of others.
Well, think about it. Who created the earth and everyone on it? I don't personally believe an explosion came out of nowhere and we were magically created. And think about the bible. It has survived thousands of years and many people believe in it. It's really up to you but I believe in God.
