Okay I have a non techy answer.
We are searching the data spectrum for signals in a specific mhz
range. This mhz is the one that, I believe, Hydrogen atoms vibrate.

This is correct, so far.

Meaning that any communication recieved would be from life forms that
have Hydrogen based life, like ours.

This is where is goes wrong, the hydrogen band is cleaner. There is less noise in this part of the spectrum so if you wanted a message to travel far and not get swamped with all the background noise then this is the frequency you should transmit at. Likewise this is the frequency to listen on for other peoples messages. You only need our level of technology to discover this, however to transmit a message is somewhat beyond our means.

BTW: I am carbon based as are the rest of earths inhabitants.
