When I was a theist, I did not believe in aliens, as there were no mention of them in the Bible.
Tonight, I was looking up to the night sky as a possible deist, and for the first time I got excited at the thought that there were other life forms in the vast vast cosmos. From a deist POV, belief in the possibilities of aliens is completely reasonable I think.
I wonder if intelligent aliens have a conception of God(s).
Do you believe that intelligent life forms exist beyond Earth? How does your religious/spiritual beliefs affect your view on aliens?
I think the probability is high there are life out there in some other star systems from either our own Milky Way or other galaxies.
What I don’t think is true, are the stories of aliens traveling here, to abduct or study humans or experiment on humans, or to invade Earth. These are just stories to either money, or people suffering some sorts of delusions.
Take our space missions as examples. Voyager 1 & Voyager 2, are the most distant man-made crafts, to go beyond our Solar System to interstellar space (the boundary is the heliopause, which they have crossed in 2012).
Both Voyagers have been operating for nearly 45 years. Voyager 1 has traveled 23.3 billion km, which is 155.8 AU (astronomical units), which is ONLY 0.00246 light-year. That’s no where near 1 light-year!
The distance between sun and the closest star, Proxima Centauri, is about 4.2465 light-year. Neither Voyagers are travelling in that direction...but supposed, hypothetically Voyager 1 was heading towards Proxima Centauri. It would have taken over 73,000 years to travel 4.2 light-year, at its current speed of 17.5 km/s.
17.5 km/s may not sound fast, but the fastest jet, Lockheed SR-71 Blackhead can only managed 0.9 km/s (or 3500 km/h).
So Voyager 1 is moving faster than any other craft, but it will not last for 73,000 years. In fact, Voyager 1 is predicted to lose all power by 2025, meaning it will stop sending signals back to Earth.
Considering how long it will take to travel even 1 light-year, eg at 17km/s like that on Voyager 1, over 17,000 years, manned interstellar space travel don’t seem likely for us...and I don’t see aliens doing any better.
Plus spacecraft capable of travelling at speed of light or faster, are science fiction.
Yes, it would shorter travel time, but that’s light, not manned spacecraft. No machine built by humans could match speed of light.
As I said, Voyager 1 is currently travelling at speed of 17 km/s. To put it perspective light travel at speed of 300,000 km/s. We are no where near matching this speed, and I highly doubt aliens could built ships to ravel at speed of light.
As I said, interstellar space travel is very interesting, but any thought of reaching another star is science fiction. And no machine can travel can achieve speed of light.
I doubt that even if there were aliens out there would spend tens of thousands of years space travelling to reach even their closest star system.
And as to intergalactic space travel? I don’t think so. Even at light speed it will take over 2 million years to reach the reach of Andromeda Galaxy, our nearest large spiral galaxy neighbour.
