how can I get a government job with no experience or degree? I am working on getting in school now.?

It depends on the government job you want, and what the requirements are to get it.

There are plenty of janitors and truck drivers that work for the government.

There are thousands of gov't jobs listed here: https://www.usajobs.gov/
You can set the search field by paygrade. Anything below GS5 or so isn't going to require a degree.
