What a load of crap!!!
"Raiders of the Lost Ark" was written by George Lucas and Philip Kaufman, not the guy "Endy" claims. Steven Spielberg and Lawrence Kasdan also had something to do with the final script.
Also:
The original name of the lead character in the script was Indiana Smith. His name was changed to Jones on the first day of production.
Indiana Jones's name comes from the name of George Lucas's dog and is a play on Steve McQueen's eponymous character name in Nevada Smith (1966). Indiana the dog, who was a Malamute, also served as the inspiration for Chewbacca in Star Wars (1977)

My first take on this was, it has to be an article from Scrappleface or The Onion.
Another reference regarding the history of the character of Indiana Jones. From filmsite.org - Raiders Of The Lost Ark (1981):
The swaggering, two-fisted character with a fear of snakes was designed to be flawed yet cocky, with frequent boasts: "Trust me." The character was originally named Indiana Smith, but it was changed by Spielberg. [Note: "Indiana" was the name of Lucas' dog. The swashbuckling character of Indiana Jones was loosely based on an early 19th century Italian archaeologist named Giovanni Belzoni, who became famous for exploring and excavating treasured Egyptian sites. The name was also a playful variation of Steve McQueen's name in Nevada Smith (1966).]
Check out the Google on Giovanni Battista Belzoni (I notice my Google link had "firefox" in it so I don't know if it will work for youse whats gots Netscape and IE). Quite an interesting character.
