Your heart is actually located in the middle of your chest and tilted slightly to the left. The left side of your heart is bigger and accounts for about 2/3rds of the hearts mass. That coupled with the tilt makes it easy to think it’s positioned to the left, but it is not. It’s positioned the way it is so that the sternum and ribcage protect it. The stomach just so happens to be on the left side, there is not a specific evolutionary reason behind it.
