So then - no scientist should say they believe in the existence of gravity? After all - no one has confirmed how it works. And there are lot of questions about gravity.
Some questions about gravity:
1. Most forces have opposites. Gravity does not appear to do so (no confirmed, repeatable evidence of actual anti-gravity as a force).
2. Why is the force so weak?
3. Do gravitational waves exist? It is generally assumed the answer is yes, but there was no actual evidence until the LIGO experiment in 2015. It was confirmed with a completely separate apparatus in 2017.

But with all the questions - scientists do believe gravity exists.
