Our knowledge improves over the years, last time we used to believe the earth is the centre of the universe, the Sun, the Moon and all the stars orbit the earth. It turned out to be false.

Now we think we are the only planet in entire universe that has living beings….and we are the most intelligent creatures…again, this is not true, hopefully we will find aliens in other parts of universe.

The problem is they are too far away from us.
The nearest earth like planet that is near to the Earth. Base on current space shuttle speed, we need 2000 donkey years to reach there.
