Funnily enough, when they first meet past the edges of the Sol system, the aliens like the humans.
None of the humans were prepared for this.
The humans prepared for decades- for centuries! to contact life out in the black, and be judged harshly for their past.

“You see, we heard you calling out for long, long, long… we could not find where you called out from. Now we have! You called for so long, and now we meet you! It is good to know you! We have tried so hard to find you and say, Hello!”
The messages Earth sent out, just in case there was anyone out there to hear, to extend reassurance that they simply were not alone was received always with delight. And they sparked a soft race to find the origin of such a kind and curious signal into the vastness of the universe.
