Tomorrow is Wow! plus 45 years. https://en.wikipedia.org/wiki/Wow!_signal
Personally, I would prefer direct one to one comunication, “So Earthlings, we’re over here a blue zillion light years from you, but we can be there friday next for the Elvis concert if you’d like to meet & greet. We’ll be the ones with the long dark hair, sunglasses & the sequined pants suit with attached cape. Viva Las Vega baby. Alien out.”
Seriously, can’t wait to learn the truth about the influence extra terrestrials have had, good & bad, on Earth. Be nice knowing we had friends in high places. ❤️
