You might consider studying the Ontological Proof of God's existence which was developed by Rene Descartes:

From the University of Toronto

And St. Anselm also wrote on this subject.

As for me, I say just take a walk in nature and look around. Is it all accidental? Pure chaos?

Oh, it is accidental, huh? Then please explain why mathematics, science and astrophysics all work so perfectly. And even chaos theory may be proven mathematically.

Reality exists in the mind of God.

Here is St. Anselm's ontological proof:

From Princeton University

St. Anselm's proof is easier to digest and understand than Descarte's proof.

After you get through all of these meditations, you might take a peek at Kant and Heidigger. Might take a few years to get through all of that, though.
