I'm not sure why you're being down voted. Do others not realize how loud the sun is? Even trying our hardest to send messages it is like playing a rock concert next to a rocket. Loud, but even with the amps to 11 you're gonna just drown out in the background.

Not to mention that lightspeed is slow. Even to Proxima Centari it will take several years for that signal to reach its destination.

This is also the great challenge of SETI. It's quite possible we've already received alien signals but just can't differentiate them from all the noise. I know they say that in space no one can hear you scream, but the sun is screaming at the top of its lungs and it is a thing bigger than you can imagine.
