If all religions are based on a reality, what happens when that reality is made into science?

If spirituality is broken down to a science, would that mean the end of religion ? Wouldn't that save many lives (at the very least it would end beheadings)? If a young man, who actually loves a woman (can point to her THROUGH WALLS); I can stop your devolution. I can help save many lives. Please help stop my people's extinction.
