It's repeatable. It's what you can see, what you can touch, what you can count and measure.

Science is a theory that you keep trying to disprove.

Peer review

Out of all the systems humans have come up with for knowing, science has the best track record. Also the ability to change when new information becomes available puts it a quantum leap above any static knowledge system.

The basic premise of Science is test and test and test. Ask the question is this working, is this supported by data. Can another person get the same result? Can another, and another, and another? If all this work gets done, it is still open to research and testing. Einstein came up with some ideas and no one took them to be true until they were proven to be correct. Wee are still putting all this under scrutiny and we have technologies which rely on the fact that the theory is correct. We are still researching this as there may be something wrong. If there is then we will change our theories and we will have discovered many other facts that have been proven to be true. If all of a sudden we find that the speed of light can be broken, then this will change the way we look at certain aspects of the theory. It does not mean that if we find ftl travel to work that our cell phones will quit working. Try this with any religion and you will see a difference immediately.

Because it admits when its wrong unlike religion or Comrade Trump

Because everything else is just guessing without checking the results. At least science checks the results.

verifiable, replicable, falsifiable . . .
