Almost like it’s the Easter bunny or Santa story as bad as that sounds but then if I didn’t believe at all then why else would I be so afraid to go to hell or to be left behind.
That's where the problem is. You are confused because you accepted modern education which is facilitating a lie. Easter bunny and Santa lack human testimonies, while Jesus has eyewitnesses who are willing to die and martyr themselves for the truth to convey. Modern education emphasizes evidence by neglecting the even more powerful and fundamental way of truth conveying which is faith in human testimonies.
So the question needs to be asked in a reversed order such that you can penetrate the lie and confusion caused by modern education.
If God is true how would you know?
1) God shows up publicly, such that every individual knows
This way God breaks His own covenant with humans, as the New Covenant specifies that humans need to be saved by faith and faith alone. So if God shows up publicly then no men can be saved.
2) Through those eyewitnesses who ever encountered God
This is a fundamental way for humans to get to a truth of any kind, as humans lack the capability to actually gather evidence, especially historical evidence. Humans don't have the ability to identify whether someone actually encountered God. So do you want to wait for human technology to grow such that humans can identify whether the prophets actually met with God, or whether the disciples actually watched Jesus performing miracles?
This may take zillion years till humans can truly acquire such a kind of technology. You are long dead by then, and cannot be saved even if God and Jesus are real. Do you want it this way?
The other way is putting faith in what the eyewitnesses said, as it remains the only way for you to get to this truth. Maybe to your surprise (as a result of the brainwashing education), it is a fundamental way for you to get to the truths of any kind. For example, covid-19 death tolls have been listed on a daily basis for more than 2 years now, that is more than 2x365=730 days. Which day's figure do you actually have the evidence? When it is said that there are 10,000 died on a particular day, do you actually verify it to have a name list of those 10,000 humans who died? You don't, you either trust the figure with faith or you do not. There's no way for each human to fact-check the figure individually. What 99.99% of humans can do is either swallow the figure or refuse to believe it. Nonetheless, this remains the only way for humans in the majority to get to this truth. It is by means of faith in testimony instead of evidence, as by means of evidence is completely impossible! The figures are actually in the form of testimonies from those small groups of humans responsible for counting and collecting the data.
So even when God and Jesus are real, the only way remains for humans to get to this truth is by means of putting faith in testimonies (as we did on covid-19 death tolls). There's no the other way round.
Now why the miracles?
How can God identify Himself being a God at all? He must do something humans can't or are incapable of doing in order for a human to know that He's God. Generally, humans can't do two things, 1) to tell a future, and 2) to break the physics laws governing our universe. That's why you see prophecies and miracles whenever God is around. Not only prophecies and miracles can identify who God is, but also they are used to authenticate a prophet for the messages this prophet is trying to convey. That's why you see a lot of miracles performed by Jesus, as the message He's trying to convey is crucial to humans.
Now you may just overcome the confusion introduced by our education and realize that truths to humans are not conveyed by evidence. 99% of truths are conveyed to humans in the majority by means of faith in human testimonies. "Evidence" is just an ideal that humans can hardly achieve in reality. Satan introduced this ideal into our education to brainwash and confuse humans. Just as the Bible predicted,
2 Corinthians 4:
4 The god of this age has blinded the minds of unbelievers, so that they cannot see the light of the gospel that displays the glory of Christ, who is the image of God.
Romans 1:
25 They exchanged the truth about God for a lie, and worshiped and served created things rather than the Creator—who is forever praised. Amen.
