But isn’t there studies saying that 30%-50% of water predates the sun

That's not what you said. You made a blanket, absolute statement. I pointed out that the age of the water we drink is not absolute, it varies considerably.

Since everything came from the big bang, they are technically the same age

If we think of it like that, then single molecule of water can be classified as water, but a single molecule of dirt can’t be classified as the earth.
My point though was that the water we drink has been water for far longer than the earth has been the earth.

Not necessarily. The hydrogen and oxygen in water get separated and recombined all the time. It happens during photosynthesis, at high temperatures, when water is exposed to certain kinds of radiation, and all kinds of other natural processes.

Not necessarily. There are many chemical processes that destroy and create water. Burning wood or fossil fuels, for example, creates water as well as CO2. Photosynthesis breaks water and CO2 molecules apart and recombines them into sugar. Our own bodies are constantly performing both hydrolysis and dehydration reactions, which means that you may be secreting water molecules that are only a few seconds old.
