I think we did go to the moon.
The shadows are inconsistent because of the inconsistent nature of the surface they are falling on. Also, there are 2 light sources. The sun and the earth - remember, earthlight is much brighter on the moon, than vice versa.
- So the shadows are exactly as they should be.
They left a laser reflector, and to this day, the distance between the earth and the moon is checked daily (we are gradually drifting apart).
RE. UFOs - Yes, most have a simple and scientific basis. ie. the black triangles, belgian sightings etc.
Some, as yet, do not.
When you think, there are more stars in the known universe than there are grains of sand on every beach on the planet - many of these must support life (Drake equation). Given our exponential advancement since the dawn of our technological revolution, what about societies which have been in theirs for 50,000 years ? Can you imagine ??
Perhaps it would be improbable that they wouldn't have stumbled upon us !
Or perhaps I should spend less time wondering
Ps.Interesting stuff, Ribble-Valley - Bet that was amazing. Did it look military ?
