Hence No Aliens... probably 95% no...
Everything isnot moving away from just the Earth.
In fact everything is moving away from everything else - that's the nature of expansion.
Imagine dots on the surface of a balloon slowly growing further apart as it inflates. There is no single dot that everything else is moving away from - they are all separating from one another at an equal velocity.
But if you look at any one dot it will appear that it's stationary while all else moves further away.
Saying that all is moving away from us is akin to saying the Sun orbits the Earth, and even the vatican has given up on that one.
Relativity is a cunningly deceptive concept - simple, yet illusive.
