Yes it was a bad ideal as it makes it harder for what we call aliens that have been living on our planet and every planet in our solar system for millions of years to protect us from other aliens that have other things in mind for us such as using us for a food source like cattle in a pin

Sending out signals is like ringing a dinner bell for some of those aliens they protect us from and if it rings at the wrong place they will not be able to protect us at all from what I heard straight from the horses mouth

I was told billions could die before they could stop it that is if they could stop it at all so it is probably not a good ideal to be ringing dinner bells in the galaxy when you will be the food on the table
