Older than any of us alive today, it has been on earth as long as we know that life has been of this planet. So we are technically drinking water that the dinosaurs used to drink. The water goes through the water cycle so it gets purified and is able to be reused once more. Yet again the oldest water droplet every found is at least 4.5 billion years old
