could you explain more about that?

well, present perfect is used when we are talking about sth which we have done but the time doesn't matter; let me explain the examples:
Have you ever eaten Moroccan food?
Possible answers:
- Yes, I have. I have eaten Moroccan food---------> Have I mentioned the time? no
- Yes, I have, I ate it once in Paris-------> I've mentioned Paris here which means that I'm talking about past n a specific time in the past so it is answered with simple past.
- Yes, I have. I ate it some years ago in paris------> that is exatly like the above example
----------
when u use present perfect with 'since' that makes it sorta meaningless bcuz u r mentioning an action which u are still doing; so in such cases u have to use Present Perfect Continuous...so: I've been doing this sport since 2001/ I was a child....
n sometimes when u wanna emphasize on sth u should use 'present perfect continuous' as well: e.g: I''ve been waiting for you for about an ahour----> in such a case u wanna show that u r sorta angry bcuz of yr partner's delay
instead of this sentence can we say: It lik
es a real war
I dun think so, because like as a verb doesn't refer to similarity
And whats you idea about that sentence in my post:
Is it wrong again?
Used to refers to the past: I used to wake up late
be used to doing(I am used to/ he is used to): refers to the present; I'm used to getting up early--> right now I have no difficulty with waking up early
get used to doing refers to sth which u r getting familiar with day by day; I'm getting used to waking up early---> I may still have some difficulties with waking up early but it's getting easier n easier each day'

By the way, present perfect is not tangable, there are so many English-learners who can never feel it, but let me tell u in both speaking n writing it is really common among native speakers
