Do you drink the same water that was on earth millons of years ago?

Yes, the water we drink today is part of a closed system that has been recycled through natural processes for millions of years. Water evaporates, condenses, and returns to the earth as precipitation, continually circulating through the atmosphere, rivers, lakes, and oceans. This means that some of the water we consume could have existed in various forms long before human history. Thus, while the specific molecules may not be the same, the water itself is part of an ancient cycle that connects us to the distant past.
