We cannot rule out the idea that intelligence agencies analyzed samples from alien craft or even the alien itself, dead or alive. Scientists are the ones researching these questions, and they are obligated to share their findings with us.
Three massive spacecraft are getting dangerously close to our world, according to SETI, the Agency for Extraterrestrial Intelligent Research. The largest is 150 miles long and 150 miles wide.
The HAARP space survey system, created to investigate northern light phenomena, observed these objects.
Other claims indicate that these objects are extraterrestrial satellites that will be visible from Earth after passing through the orbit of Mars. The arrival of the ships will be the first time humans have come into contact with alien races in history.
