Once you figure this out. You will know the reason God flooded Us Back When Joesph made a arch.

That One Animal. Made Us all angry and untruthfulness. Never think of him in a good way. He Gave us the worst Virus known to man. He gave us it to make us fall. That Animal Is devious, Ugly, Scary, Known to all.

(I made this. And i think this is the best one i have made in these so far.)

First sentence: Incomplete, change period to a comma, merge with sentence two.
Second sentences, back, and when are all capitalized unnecessarily. A should be an. Arch should be ark.
Third sentence: One and Animal capitalized unnecessarily. Incomplete, change period to comma, merge with sentence four.
Fourth sentence: Us is capitalized unnecessarily. Untruthfulness should be dishonest.
Sixth sentence: Gave, and virus are capitalized unnecessarily.
Seventh sentence: Rearrange words: "He gave it to us to make us fall."
Eighth sentence: Animal, is, ugly, scary, and known are capitalized unnecessarily. Should have an 'and' before known.
Ninth sentence: Merge with tenth, correct tenth's grammar and capitlization to make: "I made this, and I think this is the best of these I have made so far."
