You conflate the universe having a creator with the Bible being divinely inspired.
I'm going to grant, for the sake of argument, that the universe was created by a sentient, even person-like being. It doesn't follow in any way that the Bible - a collection of books assembled in the 4th century, centuries after the source material, which was a collection of legends to begin with, was written - contains any true statements about this being, much less that it was somehow "dictated" by him so as to be 100% true.
There's three steps here:
1. The universe had a person-like creator (granted as a premise).
2. Certain human books contain true statements about that creator.
3. That creator guaranteed those books to be 100% error-free.
You will never make any progress from 1 to 2,3, nor can you possibly do so.
Well, maybe you experienced legit miracles. I can't know. I do have my own experience to share, though:
It says in Mark 11:22-24 (also Matthew 18, John 14):
The husband of a woman I knew was diagnosed with cancer. I prayed for his recovery and survival every day for weeks, but he died. This invalidates a very specific claim Jesus made about the power of prayer.
This is a consistent experience people make: prayer is promised to move mountains, yet we have no instance of the laws of physics being violated in a clearly visible way as a result of it. When people claim healing as a result of prayer, there either (a) was medical intervention, (b) the story can't be verified, (c) it turns out there was no healing at all, or (d) the condition was one which was known to get better on its own. There are no cases of lost limbs being restored. Why? Are amputees evil people? Do they not have Christian friends and family who'll pray for them?
Or what about people praying for safety in war? Has any marauding army ever been smashed by meteors from the sky before it could reach some city and rape and murder to its heart's content? No. I guarantee people prayed for that to happen, though.
"I felt God's presence" and such are paper-thin rationalizations. You didn't feel God's presence; not really. He never audibly talked to you, he never did obvious miracles, he never visibly appeared. All anyone is ever left with is either nothing whatsoever or some vague emotional experience that he attributes to the Holy Spirit. If there were a real, human-like God visibly interfering in human affairs, we'd know it and there's be no doubt whatsoever. It'd be like DnD, with prophecies, divine spellcasting, angels, healing… the whole 9 yards. Instead, we have people talking to themselves about muh daily bread every morning, and nothing happens.
