Do memories exist even if you forget them?

I do not think memories exist after you forget them because memories are something that exists inside the mind of someone. Memories are memories because they are not facts, but are things that people experience and remember. If people do not remember memories, there will be no place where they are written down and kept. The literal definition of memories is “the faculty by which the mind stores and remembers information.” Memories are something that is left behind in a person’s mind, and after it is forgotten by all the people who experienced it and remember it, it eventually disappears.

If a tree falls down in the woods and there was no one for miles to hear it, did the tree actually make noise?

If the tree fell down in the woods and there was no one for miles to hear it, the tree would still make noise. This is a true fact that would not change. It doesn't really matter whether or not someone heard the tree fall. The tree would still make noise whether or not someone was there to listen to it fall. Just because someone was alone in their house and they screamed while there was no one for them to hear them does not mean they did not make any noise when they screamed. The fact that they screamed is still true and it would still be backed by science.

If there was no good in the world, then would evil be right?

If there was no good in the world, evil would still not be morally right. Just because everyone was doing wrong does not mean that makes it right. Good and evil is not something that could be changed. Unlike comparing heavier and lighter, good and evil is not something based on relativity. It is based on something definite, like truth. Comparing things that are heavier and lighter are things that are based off of things that are around whatever you are comparing. For some people, 500 kilograms might be light. However, if you compare someone that is evil with someone that is more evil does not make the less evil person good.

Where is the line between insanity and creativity?

I think the line between insanity and creativity is where things become unreasonable. An insane artist named Yves Klein sold an invisible painting saying that it was his artwork. This is an example of creativity becoming insanity. Being creative is coming up with your own ideas and creating something different and unique. However, being insane is being unreasonable and creating things that are unexplainable. I do think being too creative could lead to someone becoming insane. If someone keeps encouraging themselves to be creative, and goes to a point where they do not know the line between what is creativity and what is insanity, this could lead people to become insane. I think creativity should have a certain limit. Even for people who do dares online, there needs to be a line between creativity and insanity. Some people die trying to complete these dares thinking they are being creative and creating something new. There should be a line between what insanity is and what creativity is.
Do people really have free will?
Yes, I believe that people have free will. There will always be another choice, not just one. Even for things that seem “mandatory,” there is the choice to not follow that. People have free will because even if someone is being forced to do something, they will always have the choice to disobey that rule or not follow it.
Can artificial intelligence be creative?
No, I do not think artificial intelligence can be creative. Artificial evidence is something created by humans, and is meant to take the information that is inserted and use that to get answers. If AIs only use information added by humans, it cannot be creative. Being creative requires a person to think using their own brain and create something that the world has not seen before. However, since AIs use only the information added to it by humans, it cannot create something that the world has never seen. Even if it creates something new, it will always be a different version of something people have already experienced.
