But sci-fi movies have taught us multiple times why changing the past is a bad idea so let's not do that for now lol

If someone went back and changed their past, they’d probably create a new present from that moment.If some goes to his/her past and change something in his/her life will he or she still in his or her past or started new present there ....
Yup buddy ... We need to focus on what we can do, rather than contemplating what we can not.If someone went back and changed their past, they’d probably create a new present from that moment.
But honestly, if I ever get a time machine, I’m not fixing history… I’m going back to stop myself from saying stupid things, trusting the wrong people, and sending embarrassing messages at 2 AM.
Still, the funny part is… if we changed all our mistakes, we might also erase the lessons and the people that shaped us.
So maybe the past isn’t something to edit… it’s just something to laugh at later and say “wow, I survived that.”
