First Please dont accuse me of not paying attention!!(motaham be bitavajohy nakon
Second:about that cave men everybody can come and testify(shehadat bede)that you made me so confused by notonly your english explanation butalso by persian explanation!!!that i hardly(besakhty)understood what was going on(mozo che bood
Third.Its you that should pay a very careful attention that all these topics and the works done here are just to make you speak english more and increase your vacabulary in one sentence to make a free discution class for free it means free of charge!
?Do you know anything better than this in the world
After kidding now look at your mistakes:
1You didnt pay attention.attention is a noun not a verb
2human kind (noe bashar ya noe ensan) is wrong in your sentence,you should say;Humans(ensanha )
3with a nice style ;attention we need to use indiffinite article(harfe tarif) many times in english sentences while we maybe dont think such a nessasity(zarorat) in persian sentences having (ba dashtane)exactly the same meanings(daghighan haman manyha)
Warning:If he does those words is wrong in english even maybe its better tosay it differently in farsy
We say if we do those works or jobs . for the noun"words" we use the vebs such as listen or pay attention so we say;If he listens or pay attention to these words which belonge to God or if we do do the works which God wants
4In the future
5In old age body is wrong we say :in the body of an old age person
old age is an adjective(sefat ).we can use it in another way:in the bodies of the old.here the old is a noun wich comes with the and its meaning in farsy is;pirha Good luck
