Michael Jackson DNA Test -- Organizer Insists Results Are REAL ... We Doctored Logo to Make it 'Pretty'

The media mogul who organized the DNA test allegedly proving Michael Jackson fathered a son in 1982 insists the results are 100% real -- despite using a laboratory logo that's obviously been doctored -- telling TMZ, the logo was altered to make it look prettier.

Billionaire Alki David released the so-called "results" live on the Internet Thursday -- and after TMZ obtained a copy of the document, we discovered the logo on top wasn't just fake ... it was ripped from "Terminator Salvation."

Now David tells us, "The logo was made by the DNA agency to make it look pretty. Lab documents are not pretty by nature." He also says the results are private and were never supposed to be released to the public.

Which doesn't make sense on several levels -- David's doctored logo doesn't make his "lab results" any prettier than other lab results we've come across ... no offense ... and if the results were never supposed to be released publicly, why bother making them look nice?
