Why do you believe God considers this a problem? Why don’t you consider it as one of God’s mysteries and just part of His plan?
Two reasons. One, he refers to sin throughout his word as a “problem”. He did not want us to live eternally apart from him so he kept Adam and Eve (and the rest of us) from the tree of life. Two, if he did not consider sin a problem, why did he offer himself as the solution?
Debate is pointless, though. If you truly want answers from God, ask him. He loves you and has given you his word (the Bible) to help you. He does not hide from those who truly seek him.
