What if aliens visited Earth?

So, I was watching a documentary about space exploration the other night, and it got me wondering what would happen if aliens actually made contact? I’m fascinated by the idea, but I’m also curious about how we’d handle it as a society. Would it bring us together or cause chaos? And from a holistic perspective, how might their presence affect our well-being and the way we see ourselves in the universe? Has anyone else thought about this or come across interesting theories?
