Why is the human body is symmetrical in exterior, but inside the stomach and heart is on left side? what advantages does it give to us?

The heart isn’t on the left side- it’s located central behind your sternum and nestled between/on too of your lungs. The organ itself is not symmetrical so it sticks out further to the left.
Missed by most of the other comments is the advantages that asymmetry gives to *starting* locomotion. Walking on two feet or four requires twisting a spine, which means half the body has to rotate forward while the other half rotates backwards. Our internal asymmetry is an inbuilt twist that biases planting a right foot and swinging a left, using gravity and internal torsion to start walking. Basically it’s more efficient.

I hate to be the bearer of bad news, but your heart is in the middle of your chest. It may lean on your diaphragm and list to one side or the other, but your heart is in the middle of your chest.
The heart is located slightly to the left of the center of the chest,
while the stomach is located on the right side of the abdomen. These
positions are thought to be the result of the way the body develops
during fetal development, rather than being due to any particular
advantage they provide.
The heart is not on the left side, it’s in the middle. The left half just is just larger than the right because it has to pump blood though the entire body instead of just to the lungs
