Leave the poor guy alone because he'll probably turn out to be a paid actor if Elenin hits . Your real business would be with NASA and the US Government who lied to you.
3600 year orbit been confirmed yet?
Given the orbital eccentricity of this object, its orbital period is not a fixed value, because it is frequently perturbed by the gravity of the planets. Near perihelion, using an August 2011 epoch, Kazuo Kino#a shows C/2010 X1 to have a heliocentric orbital period of 600,000 years, though more perturbations will occur. For objects at such high eccentricity, the Sun's barycentric coordinates are more stable than heliocentric coordinates. The orbit of a long-period comet is properly obtained when the osculating orbit is computed at an epoch after leaving the planetary region and is calculated with respect to the center of mass of the solar system. Using JPL Horizons with an observed orbital arc of 235 days, the barycentric orbital elements for epoch 2020-Jan-01 generate a semi-major axis of 518 AU and a period of approximately 11,800 years.

Wait, now the Navajo supposedly have a prophecy as well? People need to stop creating these false prophecies and then assigning them to indigenous cultures to boost their credibility.

Exactly the opposite; it has been definitively ruled out:
You need to read the information presented in DJW001's post again.
"has been definitively ruled out:"
your both,,full of #.
