The universe exists and needed a creator and designer.
Why? That doesn't follow. Explain this need.
Life exists and needed a life giver.
Why? That doesn't follow either.

You don't believe these things so why would you believe the description of God in the Bible. Plenty of people have experienced the supernatural and miracles from God.
But are their experiences consistent? Are they reproducible? Are they verifiable, or even measurable?Are they consistent with known, physical realities?
I can walk into a mental hospital and find half a dozen people claiming supernatural experiences and divine insight, but without inter-claim consistency or congruence with objective reality, would it be rational to believe them?
In re: descriptions of God in the Bible: The description is of a seriously disturbed monster.
Ignoring witness reports of the supernatural is an error. If it is rational to not ignore these and to conclude that they were real and to believe in the same God and trust Him, that is my faith and how it is rational.
What makes these many times removed, many times retold and recopied accounts reliable, especially when the claims are fantastical, word of mouth and many times recopied -- usually by scribes with an agenda.
Any forensic investigator will tell you that even first person accounts by eyewitnesses are notoriously inconsistent and often at odds with the actual facts.
After thousands of repetitions, cherry-picking of preferred narratives, and editing, these accounts are not reliable evidence for anything. Basing a belief system on such accounts is
not rational, it is faith.
Of course but you have no faith in this God and the description of Him in the Bible and the long term good that is coming from all of God's decisions.
Unevidenced belief: "faith," is not rational, and a reasonable person would defer belief, pending actual evidence.
I also take exception to your claim of long term good. History and current events seem to contradict this.
You see this God, if anything, as just on the level of any human.
I don't see this God at all, but by His description, He's certainly not on a level with any ordinary human.
Perhaps a Genghis Kahn, Pol Pot or Ivan the Terrible....
