Sounds like good, and well considered advice. A good start. Good for a laugh but also an interesting thought problem.

Great "article" Interesting things to consider!

Lol, I'm guessing if anyone want to make contact with us, they probably know how to communicate with us already, so that's taken care of.

As long as it doesn't involve any probes, it would be interesting.

If I make first contact then I'll whip out the Universal Translator that I keep in my ETPSK.

Then I'll say something worthy of history, such as:

"Klatu barada nikto!"

That hilarious. If they can make it here though, we're probably toast. Why come all that way to share a planet? I suppose if we're lucky it'll be quick and painless. "Look, its an alien space......."

"Klaatu barada nikto"

"Klaatu... verata... n... Necktie. Nectar. Nickel. Noodle." Don't blow it Army of Darkness, great movie LOL

I always have a sweeping soundtrack at the ready, just in case.

Should we be stocking up on Reese's Pieces? It was supposed to be M&Ms but the Mars Company said no - now there is a conspiracy theory in the making.

Quatermass Conclusion TV series was certainly a antidote to Spielberg's Close Encounter of the Third Kind in the late 1970s.

Under the humor, that's actually pretty good advice.
