John and Doves,
Thanks Donna for alerting us to these dates 93 years apart that could both be related to alien (demonic) appearances.
Yes the two dates are exactly 93 years apart ot 31+31+31 years. (13 backwards? 39 backwards?)
The day gap for 93 years is 33,968 or (193 + 193) x 88
Can't see anything particularly significant there though.
