Re: so tell me honestly...
Yea_Boi, I will provide you 2 explanations for this, both from different perspective but not unrelated either.
1) Before we came to this world, our creator Allah (swt) made a covenant with us and tested us as stated in the Holy Quran:
[7:172] And when your Lord brought forth from the children of Adam, from their backs, their descendants, and made them bear witness against their own souls: Am I not your Lord? They said: Yes! we bear witness. Lest you should say on the day of resurrection: Surely we were heedless of this.
Many aspects of our lives in this world and our test here is related to Alam e Dharr/Zurr. This is a lengthy topic and you may wish to study it in the light of some other verses of the holy Quran on similar theme and also the teachings of the Prophet Mohammad and his Ahlul Bayt who have eloquently explained this topic among many other relevant topics such as Adl or Justice of Allah (swt).
2) One simpler way to look at look at this is to look at how some of us are born in rich families while some not. Some are born perfectly healthy and some with deficiencies. Some have a lot of strength whereas some are weak etc etc.
The test for each of us is what we can do with what we are given. If you are rich/healthy/strong then your test is mainly of 'shukr'. On the day of judgement you shall be questioned about what you did with what you were blessed with. Whereas if you are born poor/unhealthy/weak then its mainly going to test your 'sabr' and steadfastness in the way of difficulties.
[2:155] Verily, We shall put you to test with some fear, and hunger, and with some loss of wealth, lives, and offsprings. And (O Muhammad) convey good tidings to those who are patient, who say, when inflicted by hardship, "Verily we are of God and verily to Him shall we return;" upon them is the blessings of Allah and His mercy.
If a child is born a believer, and specially a follower of Mohammad and his Ahlul Bayt, then s/he will be questioned especially about what s/he did with this 'naimat'. And just like a strong person is expected to help the weak, a believing person is to carry a lot of weight on his/her shoulder and strive be a shinning example of 'haq' wherever they go or whoever they deal with.
