Hi Ramy. Great job! You writing shows you have a good understanding of common English expressions. Please consider the following adjustments regarding the use of prepositions.

English is one of the easiest languages all over the world, also it's the most popular language all over the world. 

English is one of the easiest languages in the world. It's also the most popular.

[To use a more common English expression, we could use the phrase "easiest IN the world". The prepositional phrase "all over the world" is more often used to suggest something happening in many different places. Ex. "English is SPOKEN all over the world." Also because we usually avoid repeating phrases from one sentence to the next, we can simply say, "It's also the most popular" and the idea that English is popular worldwide is still understood.]

In Egypt, English is the first foreign language that many of the Egyptians can write, read and speak with.

[The verb "to speak" does not need the preposition "with" when the action is "speaking a language". Ex. "Do you speak Arabic?"  The preposition "in" is used in some cases. Ex. "I overheard them speaking in French." The preposition "with" is only used when "to speak" means to communicate with another person. Ex. "I'd like to speak with you for a moment." Also, we do not end sentences with prepositions; this is a grammar rule, though it's often broken even native English speakers.]

I think learning English gives me a great better chance to communicate with people all over the world, to learn more about life and to enjoy English movies, books, novels, and music. [Good.]

Keep up the good work!
