Forever.
The concept that explains this is the water cycle. Water on Earth is constantly recycled through processes like evaporation, condensation, and precipitation. This means that the water you drink today could have been around for billions of years, as it has been part of the Earth's water cycle for a long time.
NOBODY REALLY KNOWS...........
Yes, it is safe to drink sterile water as long as it has been properly sterilized and is free from harmful contaminants.
Yes, it is generally safe to drink the water from a brown coconut as long as the coconut is fresh and has not been contaminated.
Forever unless you have treated the water to make it potable.
Not so much. All of the water that has ever been on earth has been recycled through evaporation then rain or snow and so on since the earth began. So dinosaurs drank water and peed and the water was absorbed into the ground which filtered it and then it rose to the surface, evaporated, rained and so on. So yes it is the same water the dinosaurs used but any trace of dinosaur pee has long ago been filtered out.

Yes, it is safe to drink sterile water for hydration as long as it has been properly sterilized to remove any harmful bacteria or contaminants.
Yes, it is generally safe to drink water from a brown coconut as long as the coconut is fresh and has not been contaminated. The water inside is usually sterile and safe to consume.
they can drink as long as 20 min.
Nearly all the water on Earth has been here since long before the dinosaurs. It is constantly recycled via the water cycle. During the millions of years that dinosaurs existed, at least a good portion of the water molecules on Earth passed through a dinosaur at some point, only to evaporate and rejoin the water cycle. So, at least some of the water you drink was in a dinosaur at some point.
Potable water is water that is safe to drink without causing long term health issues. The water that comes out of your sink is potable water meaning it has been treated for bacteria or other harmful substances and is deemed safe to drink.
