Two Identical Serpentine Celtic Sun Temples in Germany and Newark, Ohio.

Henge on the left is in German and the right from a small circult work at the Newark, Ohio earthwork.www.nephilimgiants.net : Ancient Henge (Sun Temple) Discovered in Germany with Links to the Ohio Valley

Is it a coincidence that these two Sun Temples are nearly identical?ok at the serpentine gateways.  This is evidence of the migration of the Nephilim (Amorites) giants from Europe to the Ohio Valley. 

The large Henge at the Newark works also has a henge with a serpentine gateway. Do you think this is serendipity?  The logical conclusion in that it was the same people that built both of these sites.
