I’m not quite sure what you’re asking. We were talking about searching for signs of extraterrestrial life by looking for electromagnetic signals that they may have sent through space.

Are you asking why I’d assume that they don’t have the biological ability to send electromagnetic communication signals?

If that’s not what you’re asking, I don’t understand how else they’d send signals through space without sophisticated instruments capable of transmitting powerful signals.

Please clarify.
