But free will cannot exist with an omniscient god, because if he knows everything, then everything is predetermined, giving us no free will and also making god evil for allowing all the suffering to happen. And if free will does exist god isnt omniscient

According to the Bible, God never gave man free will. He only gave us the free will to accept the knowledge of actions. However, it reads more like how you would think of a child as innocent – humans didn't know what was good or bad. Of course, the Garden of Eden was never real and the story was just a story.

However, the Bible also states that the reason we have free will is because love and good aren't forced. You can't love someone or perform a good deed if those are your only options. You have to choose to do so. The angels also had free will which is what led to Lucifer and his followers.

I'm not religious anymore, but my parents are still super Catholic. My dad taught Sunday school growing up and still works for a church while my mom is a teacher at a Catholic high school.

Without free will, true worship cannot exist. (If God is God, he certainly has the right to create us for the sole purpose of worshipping him.)

To your latter points, I agree that we know clearly what evil (a.k.a sin) is—sin is anything apart from God's character (e.g. the fruit of the spirit to start).

However, it's not up to us to "get rid" of evil, that's on God, and that's exactly what he did when he sent his son Jesus to die on the cross as a substitute for the punishment we deserve, and when he rose from the grave he signified that substitution was complete. If we truly accept that fact, then God considers us saved ("redeemed"). And, one day Jesus will come back and eliminate evil once and for all.

As to why God allowed evil to enter the world in the first place, well, that's one of the cornerstone discussions of Christian theology, I can't easily summarize that here. In short, a redeemed world can know God's love and worship him more deeply than a world which was never fallen to begin with. (And again, if God is God, he absolutely has the right to create us—and all of creation—for the sole purpose of bringing him glory.) Here's an excellent article that explains this more fully.
