Why does "mainstream" science continue to deny the historical and on-going existence of Extraterrestrial contact with human beings on Earth?
Extraterrestrial denial within Western science and Christianity, manifests from a consciousness, in which human beings have been seduced to pursue materialistic power and oppression against one another.
Gnostics suggest that this apparent seduction, has been amplified by Manipulative Extraterrestrials which Gnostics had sought to help warn humanity about.
Biblical warnings about Manipulative Extraterrestrials
...have been censored by Christian religious cultist elites
The Bible itself in pre-translated forms, as presented by Biblical scholars, actually contains specific warnings against these apparent Manipulative Extraterrestrials, who have apparently sought to control, exploit and oppress humanity, through mass-deception.
However, translated forms of the Bible, including the notable King James Version, presumably directed by these reported manipulative entities, excluded the explicit warnings.
For example, Ephesians 6:12 in the King James Version of the Bible, used as a basis for more modern translations stipulates,
"For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places."
In sharp contrast a direct uncensored translation from Greek according to Biblical scholars indicates the following,
"For our struggle is not against [human beings], but against the rulers, against the powers, against the world forces of this darkness, against the spiritual [dark forces] of wickedness in outer space."
