      In sciences it’s really though / impossible to answer questions about why stuff is as it is. But what we can do is try to explain how things work. So we make observations or experiments and then analysis the results to make a theory of how it works, but not why.

      Gravity come naturally with mass. Anything with mass will have gravity so it exists because mass exists

      We don’t know!
      Hannah has said it expertly, we don’t know ‘why’ anything is 🙂
      We think gravity came about in the big bang. All the forces were combined at one point and split off one at a time. Gravity got the short straw and became the weakest force (but it did get to become the biggest!)
      The challenge in physics is to recombine them all into one fundamental force.We call it a grand unified theory and should be able to predict absolutely anything and everything that can happen in our universe!
      Great question 🙂
