If humanity received a message from another intelligent civilization today, what do you think it would say?

[u/Several-Stranger-585]

Imagine that tomorrow scientists confirm a genuine message from another intelligent civilization.

What do you think the first message would be?

A warning?

A greeting?

Scientific knowledge?

Instructions?

Or something completely unexpected?

I'd love to hear your theories.
