Once again, you're talking about subjective personal interpretations that give you a reason to believe, but you are NOT talking about evidence in the usual sense of being objective.
You got it backwards. One has to take the leap of faith first. They have to believe first. Then a person will find God and deepen their faith, as well as find objective truth and knowledge.
For this to be evidence, you would first have to demonstrate what God is "like." You would have to show that God has a conscience, thoughts and emotions. And then you would have to show that humans are "like" God in those respects. And then you might have some evidence that God exists--except oops, it would really be kind of redundant, once you have already objectively demonstrated that God has a conscience, thoughts and emotions. How much more real would God have to be, once you had demonstrated that?
Even if I did convince you, then I would not have convinced all the other non-believers in the world. That is one big thing I learned from an atheist. Lawrence Krauss said he would reassess if God rearranged the stars to say, "I'm here." However, one atheist wrote that people on the other side of the planet would not see it and not be convinced. Even when people met Jesus, they did not keep their soft faith. They only believed him if he continued his favors or miracles. Thus, my thinking is the only way to convince non-believers is to constantly remind them of God's existence.
So can you demonstrate that God has a conscience, thoughts and emotions without begging the question (that is, without assuming that God exists to prove that He exists, by appealing to Bible stories or other claims of God's existence)?
You can best demonstrate that to yourself. Do you have a conscience, thoughts and emotions? Of course you do. How can you do that? It's because you are alive and well and your body is the temple of your spirit. If a baby is born without life, then we cannot provide life for them. If one is born without hearing or sight, then we cannot give them hearing and vision like that which the majority are born with. We may be able to assist them through technological and medical breakthroughs, but we cannot give them what God gives the majority. Even our best doctors and scientists state that what nature or God provides is the best.
Whether or not humans admire perfection would not be evidence of God even if it were true. It could just as easily be argued that humans evolved the admiration for perfection as a survival advantage. But in reality, we don't always admire perfection. Many people prefer the "imperfect" tones created by traditional musical instruments over the pure sine wave tones generated by synthesizers, for instance. Our processing of the visual field works better when there are "imperfections" in the field of view, rather than a perfect monochromatic display.
You're looking for irrefutable evidence and God doesn't work that way. If one takes the leap of faith, then you'll get the convincing evidence. With Christianity, the Bible will take on a deeper richer meaning. God has kept some things to himself such as the beginning and end of life and the universe. For example, we will never know the true age of the Earth in this life. We can only rationalize it based on one's worldview.
So again, not evidence.
Please demonstrate the existence of "spirit" (especially as it exists apart from nature) before you try to use it as evidence of God.
So your argument is that life has no meaning if there is no God? This may come as some surprise to those who don't believe in God; it certainly hasn't been a very convincing "evidence" if it could even be considered as such.
As for the rest, it's not that life has no meaning just because this life is finite and temporal. While it is difficult to live life in that we live in a fallen world, it is not meaningless to be remembered well by others or to help someone else's life become better. We can only do the best we can with the tools God gave each individual. If God gave one near perfection in talent, ability or skills, then they will do better than others. Where this life does not matter is when compared to the permanent life of the spiritual world and living with God. Then we will regain our perfect spiritual selves and live in God's kingdom, power and glory forever.
As for demonstrating the existence of spirit or one's life energy, it would be through living life. One usually takes it for granted that they are alive or that the sun rose in the morning. However, it is a big deal when one's health is lessened or taken away. Living becomes much more difficult. Or what if one day the sun didn't rise because the universe was shaken up. This is prophecized. Even science states that we live in a universe of increasing entropy, so the universe is not eternal.
