On: Two potentially life-friendly planets found orbiting a nearby star

4 billion years, eh? Just about the amount of time we've had life here. Maybe they already colonized us, and we're descended from them.

Unless they colonized us with panspermia it’s about as likely as “intelligent design” they surely put in a lot of work in hiding the fact that they came here including engineering 3 billion years of evolution.

While possible seems a bit inefficient.
