As someone who has been attempting to learn Latin, I can say it is anything but an "easy language." The verb conjugation alone disqualifies that; there's too many different conjugations to keep track of, and tons of verbs are irregular in some way on top of that. English has its fair share of irregular verbs too, but at least the regular verbs are incredibly simple to conjugate. Latin has other annoyances too (all of the cases for the nouns and the fact you have to remember which of the three genders every noun is--at least most of its descendant languages like Spanish simplified it to two).
Sure English has frustrating qualities too. The spelling/pronunciation is crazy and the prepositions are something really hard to get a solid grasp on if it's not your native language. But in a number of ways, English is actually fairly simple; the verb conjugations are simpler than a lot of languages (and certainly way simpler than Latin), there's no grammatical gender, and the only time cases matter is for pronouns, and even then it's relatively simple.
I can see someone thinking English is harder if they have particular difficulty with the pronunciations and spellings, and if their native language is a Romance language so the vocabulary is at least much easier, but I can't say I see English as much harder than Latin even then.
