Borderline atheist needing help (believers only)?

im 95% an atheist. One of my biggest qualms with religion that has just started affecting me is that thought of the soul. i have read that neuroscience has basically proven that all human emotions thoughts happen in the brain. how could there be a soul when there is no need for one? also, memory can be lost like in Alzheimer's and other brain trauma accidents. how come those people lose their memory? memory is all in the cells of the brain. so how could there be a soul/afterlife when human thought is a product of the brain? like stephen hawking has recently said, the brain is like a computer, and when the computer parts fail, the computer dies. please only believer responses
