Bible mentions a rain throughout the world for 48 days and nights. Is this technically possible ? You need to have a cold air mass colliding with a humid air mass, cold front, warm front etc., before you can have rain. Even if you have rain through out the world at one time, there is not enough moisture around to rain for 48 days. What do you think ? Only scientific answers please

I am not looking for the answer " If God wants anything is possible"

I just got my first telescope its a Meade with a 2.8 inch aperature. It came with the following lens': 25mm, a 9mm, and a 2x Barlow.

I know the barlow lens doubles the smaller lens' magnifying power. I would like to know which lens can see the furthest. I have been using the 25 and the barlow together and don't know how far I can zoom in to see say Saturn. I don't know how well I will be able to see this planet. Will it be fuzzy or with my scope will it only be a shining mass in the mirror. Oh my telescope is a refractor. I just want to see the rings of Saturn, if the focuser is all the way out will it be clearer or not?

You start off with blue frogs on the left and green frogs on the right and a gap in the middle. YOU HAVE TO SWAP THE FROGS OVER
Blue Frogs - Only move right
Green Frogs - Only move Left
Frogs can move into a free space or leapfrog a frog of an opposite colour

For the same amount of frogs on each side;
n(n+2) - Why is this formula right for the same number of frogs on each side? (n = Position Number)

For different number of frogs:
n+m+nm - Why is this formula right for any number of frogs?
(n = No. of Blue Frogs and m = No. of Green Frogs)

People, Please,,, Let's get it together. There are alot of different things we could use besides wood for so many different things. I know I'm not the only one that knows this but when you extinguish one type of insect it causes a chain reaction that could kill many species of animal. Also, one species of insect could occupy only a small segment of forest. There is no telling how many meds and new unexplored ideas we've destroyed and will never know.Please comment.....
