No, you don't.

You can investigate the claims, gather evidence, evaluate and confirm or refute, including peer review. If the claim does not withstand scrutiny, you can discard it.

One does not need faith.

It is mostly an attitude difference. Skepticism is often regarded as being "too negative", and closing off one's mind to the possibilities. That is not correct.

If one is going to ask me to walk across a new bridge over a steep ravine, I'm not going to just "have faith". I'm going to see if I can verify it is stability, first.

That is how we navigate the rest of our lives. For some reason, some people specifically switch off that skepticism for theistic claims.
