Khaled, your question should be 'Is learning English easy?' or 'Is it easy to learn English?'.
And the answer is yes, there are some things that are easy about English. A lot of English grammar is simpler than most languages - for example:
My brother is tall
My sister is tall
My brothers are tall
My sisters are tall
That's pretty easy, isn't it? Words like 'tall' (adjectives) never change.
Of course, there are some things that are difficult in English, like with all languages. But it's not hard to have a simple conversation in English, and people will understand you, even if you make a few mistakes.
The other thing that makes English easier to learn than some languages is the fact that it's everywhere in the world - on TV, on the internet, in the movies.
And if you have any questions, there are a lot of English-speakers here on this site who can help you.
