Why do aliens always have to look and have similar biology to us?

Exactly! To date, no life has been found on any other planet or meteor. We would really like to find life elsewhere, and the most likely candidates within reach would be the moons of Jupiter and Saturn.

Beyond that you have to go interstellar. Since it would take hundreds or even thousands of years to reach even the nearest stars at the fastest speed we’ve ever achieved in space, interstellar travel is unlikely now or in the future.

Put away Star Trek and Star Wars. Aliens are not visiting us and we are not going to visit them, whatever they may look like.

Do you think life on other planets will ever be found?

Some of my readers embrace my pessimism. Some hate it!

Finding life on other planets is the Holy Grail of science. The final punch in the age-old fight between scientists and creationists. It runs deep.

It would finally prove life can exist elsewhere. To date no proof exists.

There are candidates right here in our own solar system with some moons in orbit around Saturn and Jupiter. They are going to spend a lot of money to look. They had hope for Mars. That hope faded quickly when we realized Mars is dead.

My gut feeling is on the side of pessimism, though.
