Good Old Water
This Reddit user asserts that we might be drinking water that’s older than our solar system. There was a study in 2014 that found that not only is the Earth’s water older than the solar system at large, but it may predate the sun. In fact, all of the water in our galaxy may be older than the sun.
So, does this mean we might be drinking dinosaur urine? If this is the same water that existed in prehistoric times, it’s possible. Or we have no idea what we’re saying. Can you imagine if water, like milk, had an expiration date? Regardless, this is an intriguing fun fact that’ll definitely pique the interest of your new friends.
