If you don't care enough about the topic to read on it yourself, I don't care enough about it to enlighten you.
As I said, it would be reasonable that the moon would not be viewable at all times the rain or manna happens.
I see that you don't care enough about the topic to make your point about relation between the Moon and the blood rain. And its not that I don't care but there just isn't anything to read. If you have any data and documented cases which show the Moon location at the sky in the moments of blood rain then enlighten me. I didn't find any. So, its' not like I don't care but you don't care and you event won't bother. I guess that clearly shows that you are not serious about it.
Also, the point isn't that it would not be viewable. I understand that there are clouds, but there surely must be some data that the Moon is even in the sky at the times. Even behind the clouds. Have you any data about that or does your entire theory rests on the shoulders of big assumption and nothing else?
