First Step - There exists a spiritual force, God

I'm going on the belief that there is in fact a God, he/she exists. This isn't just blind faith, there are several proofs, but I'm going on what I come to see as a truth about human nature that necessitates God.
1.) I'm disregarding the creationist or evolutionist theories, how we got here is immaterial. We exist.
2.) Mankind possesses capacity and characteristics that are counter-survival, and therefore not a result of direct evolutionary nature.
a.) Love - love is an irrational force that does not contribute to the survival of the species. The capacity for love makes man risk, dare, sacrifice, and be vulnerable. Love also leads to the exclusivity of marriage, dating, etc. that is in counter to the instinct of a species to procreate as much as possible with disregard to romance or exclusivity (unless rival males are fighting for dominance, etc.)
b.) Most of the spectrum of human emotion are counter-survival. Grief, jealously, anger, guilt, joy, excitement, etc. are all things that put humans in vulnerable states of mind and experience, they all compromise vigilance.
3.) Existential Thought. - the very fact that I can think about a higher type of power can mean that it exists. The capacity for existential thought cannot be accounted for by scientific method. It is counter-survival, doesn't serve to benefit the species physically. In my mind it can only be explained as the compass given to us to find something... and that something I believe is God.
4.) The Human Spirit and Longing -- I hunger b/c I need to eat. I thirst b/c I need to drink. I long for wholeness because I require purpose and meaning to live. I long for something that I cannot provide solely within myself. This longing to me also suggests that the thing I am longing for and seeking exists.

I could go on, but that's part of it. I'm starting with my belief that God does exist.

Now it's on to the harder part.... finding where God's footprints are left in this world, where the clues to finding a sense of God lay.

I've been raised as a Catholic... I considered myself a Catholic and a Christian. However I no longer know what that even means.

My gifts and restlessness as a seeker lead me to believe there is something I need to find, and that God is not meant to be put into a box by institutions and those who claim to be the interpreters of "right" and "wrong" from here on out, I will let God move me to my ends.
