How did you know God exists?
Who told you God exists?
Basically, the same question.
First, understand that God is knowable. He's reachable, even though He is infinite above and beyond our limited imagination.
Two, as I said previously, there's a plethora of evidence supporting His very existence.
Take, for instance, the fact that you can never
disprove His existence. Or, can you?
How did you know, God can never be confined with our limited finite brains?
Our brain can never think beyond the present moment, let alone the mystery regarding the nature of God.
Can you tell me with a hundred percent certainty whether you'll still be alive tomorrow?
Or, better yet, can you tell the thoughts of, let's say, your best friend?
What if I told you that God has through history predicted events thousands of years before anyone ever thought they would actually occur in the future?
Similarly, such events did reveal beforehand the course of action to which those future generations would pursue -- something that no human could presume to do.
If we cannot confine God within our limited finite brains, How did you know God exists?
Scientists such as astronomers, for example, do not need to travel 2.5 million light years away just to study the nature of one trillion stars in the Andromeda Galaxy. They simply need the best equipment while they remain in their closet down here.
They have never flown there because of human limitations and finiteness, but they
know the galaxy with its vast stars exist.
They can even tell with substantial accuracy how hot those stars are in their core!
Which "brain" did you use to know God exists?
Waiting for a better question, at least from my own perspective.
