You sound like me. When I was young I asked my poor parents everything. When to people die? Why do people die? Who made God? And who made the Creator of God? And who made that Creator?
My parents were so scattered they didn't know how to answer. For they were not truly believers, but God still managed to put the Truth in them. They would reply: Are minds are not able to comprehend that now, but God will give us the answers when we join Him in Heaven.
Hang in there...the answers will come. I am going to ask so many questions the Father might want more than just 1 day of rest. My questions have only been building up since I was little.
