Well, the universe had a beginning, and things that begin to exist need a beginner. So, logically that beginner could be God.
...or the universe always was, since physics as we know them tend to sway towards the understanding that matter can't be created or destroyed, simply exist in a different state. To stretch logic as bad as you just did, then "god" cold just be a little boson trying to find a particle to give mass to.
Things that are designed imply a designer, there is great design in the universe, so, logic leads to a Great Designer (i.e. God) that designed everything.
Using history and literature, we can trace back the origins of your god. We can even look back at Constantine and the assimilation of the pagan Saxons to see where many Christian rituals come from. Logic leads one to think that your part Hebrew part Roman part Greek god is a character hobbled together over a period of time to fit with and speak to the culture of the day.
Where the soul is concerned, things contained in the soul such as emotions, feeling, and will are immaterial.
1. What is a soul?
2. Activity in the brain (corresponding to different emotions, or lack of) can be seen as chemical and electrical reactions in the brain. Those same feelings can also be induced using chemicals and electrical impulses. The brain is a material thing that processes data... leading to...
If there are things in the world that exist and are immaterial, then materialism (the evolutionary concept that there is nothing that exists but matter) is flawed.
...wait, materialism is an evolutionary concept? What does materialism have to do with the change in allele frequency in a population over time?
It is reasonable to conclude that God created all that is immaterial that exists in the world.
That's not a reasonable conclusion, it's actually quite irrational. A definition of what immaterial things are, as well as what specifically you're talking about would help.
Materialism has no explanation for the existence of such things.
Materialism isn't a stand-alone philosophy. You're writing in nebulous, loopy circles.
