You can I'm sure go through many of my posts, many here know I've debated often on this board. I think
I delved into some here with JustAtheist previously. As for myself, right now, I am actually tired in life of such discussions and certainly it'd be foolhardy of me to think I could convince you of that which you willfully deny.
I will make some remarks. Namely reasserting there is a plethora of evidence. The likes of Antony Flew (and others) don't just switch positions after dedicating books and much of his life to belief set toward Atheism.
There are so many arguments and lines of evidence. First and foremost for me is the structured and orderly world that has been created, which many in their denial simply deny out-of-hand requiring those who believe to put forward arguments with more sophistication -- only to then have each in turn also denied. There is a strong denial mindset, and so again, it isn't my role to convince you out of denial. I believe based upon evidence, you disagree and deny God and believe that the material-physical world is all there is, that is where really we end and part ways. Trust me, I've done such routines perhaps a 1000 times.
By more sophisticated arguments, we might invoke Aquinas', which as PaulS pointed out, are often misunderstood in some sort of Kalam Cosmological argument (which is a logical argument I nonetheless believe holds up with/without the Big Bang which offers scientific support). Argument for an actual foundational something via potential contingecies is much more solid, which a multiverse cannot even escape. Something must have always existed which has no prior foundation, not just temporally via cause and effect but also in a heirarchical order of contingency. E.g., a piece of paper with writing on may have existed at one and the same time, yet we might say the writing is contingent upon the paper.
Given intelligence exists, this non-contigent foundational must possess intelligence of its own. Code requires a coder, information someone to have given it structure and even created the language itself, DNA is information, indeed the whole world is often considered to be on some fundamental level just organised information. Waves of energy wiggling this way or that, positive or negative, which defines the orderly world we see. Yet, then we also have quantum mechanics which highly suggests there is no such thing as passive observation of a purely objective and external physical-material world, rather it seems that consciousness constructs reality to some degree -- observation will influence the behaviour of matter behaving as particles or waves. If true, as the science suggest, consciousness must be considered separate and in its own light.
Intelligence exists as well as the physical. Consciousness. Our basic intuitions that I don't believe shouold be rejected without good reasoning -- that "we" really do exist, there is a true semblence self that continues throughout time despite our physical composition changing, that we are more or less truly responsible for decisions we make (rather than
purely physical effects). Morality. Concepts of fairness, justice, beauty, good, true meaning, purpose to life, etc.
So then, Theim provides foundations for all these basic intuitions we all have and share, something that Materialism either dismisses or relativises out of being an actual reality and as such true.
Really, as I see matters, people willfully ignore the evidence. Have buried their heads in the sand. Are blinded. Hence as Newton reported in his now famous Amazing Grace song, "
was blind, but now I see" -- something many, many Christians report experiencing -- being previously blind and now seeing. Previously seeing that world in black and white, and now seeing the world in colour. What are they seeing? Perhaps as Freud and Kant might suggest we see a delusion or illusion.
One side is right -- you are either blind, or we are delusional. I don't believe they/you are right. And your own evidence is thin, robs us of our common intuition in many things, such as goodness, even people's lifes being inherently valuable, etc. These questions however are important, and I pray your life's journey finishes with embracing not merely that God exists, which is good, but being restored relationally with God via Christ which is better and as I see matter a primary purpose for each of us in life. Yet, I understand that this is something you cannot contemplate or grasp where you are at in your thoughts.
