Neighboring Earth Like Planets Could Share Alien Life "Randi Thompson"

There’s only one planet in our solar system that can communicate across interplanetary space.But imagine if things were different. Say if Mars, for example, had intelligent beings able to talk to us at the same time as we talked to them — how would that have changed our history? 
 Recent press released information speculating about communication between evolved intelligent beings on such planets, but when asked about and the scenario is “improbable” — although there is  a quote to stand behind . In our own solar system, Earth is more than 4 billion years old and telescopes have only been in use for 400 years, or 0.00001 percent of that time. Even if the planets can’t share communications, they possibly could share similar biological histories. We already know of meteorites that travel from Mars and impact the Earth.
