Thank-you, xebiche, for posting your interesting comments to this forum. I happen to agree with much of what you say. The contemplative life seems to be in part about answering the questions that you posed. And, awakening from the unconscious state that having a physical body seems to "cloak" us within.
However, I am not as hopeful as you. While I do see science and religion merging, it is in fact that they are both self-protective priesthoods with impermeable membranes; and a pursuit of fantastic explanations.
Science cannot go the direction of the spirit, because spirit is non-physical, so it cannot be measured. Thus, every effort to construct a hypothesis of parallel universes fails, because scientists are not mystics, so they do not travel out of body to see the spiritual dimension.
So to answer your questions one by one:
1) No, there is no creator, nor is there a "big bang," which is just creation "science" masquerading as science.
2) There is a God, but god, is not a he, or she, or it, or entity. God is the sum total of the spiritual dimension, which pervades the physical universe, but does not direct, control or create, or modify or destroy it.
3) When we die we travel out of body into the spiritual dimension, which is as infinite as the physical universe is infinite.
4) Yes, there is an "after life". It is the spiritual dimension.
5) Humans are an animal with certain characteristics, not unlike other animals. We are spirit beings housed in a human body.
6) No, we are not alone in the universe. Life pervades the physical universe and will arise wherever the conditions for life arise long enough for life to arise there. And, life will evolve to fill every ecological niche as long as the conditions for life persist long enough, and are diverse enough to form niches.
7) God is not a being, so asking whether a being loves us is not relevant; however, the beings in the spiritual dimension are love itself, and communicate constantly with each other on a "carrier wave" of love. We are essentially love itself, but most of us do not know it, or act like it.
Thank-you for posting your most interesting thoughts, and welcome to the Fruit of the Contemplative Life,
