Good question, here are the reasons,
Human beings naturally float is because of the air in our lungs. The air acts as a buoyant force for the body, making it impossible for you to simply lie down at the bottom of a swimming pool. In the case of a corpse, however, they have no control over whether their lungs fill up or not. If the corpse falls in the water facedown, they might never sink to the bottom, as there will be no real chance for the air to escape from the lungs. However, if a corpse is put into the water on their back, air can escape, water can take its place, and the body will quickly sink.
If a person drowns, they don’t necessarily die because water fills up their lungs; often, the body will asphyxiate itself because the windpipe closes up against the presence of water.

Dead bodies tend to float after some days in water simply because the decomposition process of the body due happens to release a whole lot of gases that causes it to bloat and thus levitate it to the surface, compared to a live person or a recent dead undecomposed body

water has taking over the initially mass of flesh, blood and bones to give it buoyancy

MrSix:
I still remember physics so? Errrm
The condition for floating to occur is only when the density of the body is less than the medium it would float in or on. This all centres of the mass to volume ratio of the body.
When the body is alive, due to absence of air, the mass to volume ratio is above 1g/cm3 (density of water). So it sinks. However, when the person dies, water enters the body which causes an increase in volume, thus decrease in density of the body and a corresponding increase in the upthrust acting against the body. So it floats.

U try o but u wrong


Errrm...I try 100/10
