Perhaps the guy has an explanation for all this. And,
of course, the OFA could be wrong, or I might be
mis-remembering it.

The moon's position in the sky varies in a cycle of about
18.5 years. If you take a starting point after 18 years it
will almost return to that point and after the next 19
years it will be exactly at that point. However there is a
major problem with astronomical alignments of any
structure. That is distinguishing between intentional and
coincidental alignments. This especially the case as
computers improve and alignments become easier to calculate.

I remember when "Stonehenge Decoded" came out. Something
like 500 alignments but most were eliminated as
coincidence when the need for a clear position for the
observer to stand was figured in. After that the first
thing people investigating megalithic structures tried to
do was establish unambiguous positions for an observer and
then calculated the alignments from there.

I take it that you never heard of Tycho Brahe and his observatorium on
island Ven?
