Spoilers below.

In an hour long ep called Death Ship, three spacemen from Earth, led by one Capt. Paul Ross, find a crashed ship on a planet. Inside they find what appears to be--their very own dead selves! Identical right down to the id card one of them, Lt. Mason, finds in the pocket of his dead self(?). Back on their own uncrashed ship the Ross posits a theory. He uses a time travel theory of relativity and (he claims) that is what has happened. The three have gone into the future in which they witnessed their own death. Mason replies that is only a theory (smart man honestly)! After a couple of more bizarre happenings Ross posits a new theory. The crash ship and other strange bits are illusions designed by telepathic aliens to keep the men from reporting to Earth about the planet. Ross's 2nd dumb theory soon gets disproven pretty much along with his first and the men realize they are dead and ghosts.

End of ep summary

Now. This 1962-63 ep presents worthless theories--one real popular nowadays. That of aliens from outer space. There is no proof anywhere of them in this ep or anywhere in today's real life. All this attention devoted to it is really worthless. BTW in the ep Lt. Mason prayed to God. Now God makes sense as the Bible has great scientific accuracy. The following:

1) Water that is lifeless older than the sun

2)Man last in creation

3) Creation of reptiles before man (Septuagint version)

4) Creation of all land animals after sea life

5) Accurate descriptions of animals' habits (Lion strangles--not breaks prey's neck, leopard cannot change spots and way more)

6) Earth is round and hangs on nothing

7) Location of first civ (Mesopotamia)

8) How clouds make rain

And much more. Read a fine and true book by Ray Comfort called 'Scientific facts in the Bible" at amazon and learn way more.

PS Discover magazine Sep. 2014 has articles on water older than sun. And no--time travel is not a reality--just another stupid theory.
