Half Moon

Ever since the eclipse

I keep wondering about the moon...
And together with the game i played during that time...
I became more curious about how half moon is form...

Cox according to my stupid understanding it is impossible

So i check wiki for the answer today...
Man... I feel so stupid right now
Damn I never thought I was so stupid...

I always thought it was the Earth's shadow that cover the moon...
Then due to the Earth is round so there shouldn't be a half moon...

Man I am stupid...
I didn't even rmb the part whereby the moon is always facing you on the same side....
Awwwwwww...

The Sun is always shining on the moon at the same side and surface....
So it is because the moon position the cause the different phases....

Man.......... I AM STUPID!
