Nakosis, you're asking people to take a fair and balanced view of some group or thing. Are you not aware that our species clearly evolved its superior intelligence to fling poo better than it's cousin apes? Sheesh! Do they teach nothing in the schools these days?
Beyond that, here are some quick elaborations:
No single group in human history has contributed more to education than Christians have
Catholicism kept alive classical learning, imported Arabic learning, and expanded on both. Beyond that, Protestantism generally valued educating everyone -- including women -- on the grounds they needed to read the bible as important to being saved.
No group in human history has contributed more to healthcare than Christians have
I think it's highly arguable the Greeks did as much as the Christians did in some key ways. However you can thank the Christians for your public sewer system. Beginning in the mid 1800s London, Christians pushed for public sewer systems in country after country. In the UK and US, at least, they were joined by "muckrakers". Muckrakers were progressive journalists who specialized in promoting social causes and unmasking the excesses of capitalism. Naturally, we should not speak too much of them these days, the lousy liberals!
It's been estimated that public sewers increased the average lifespan by 10% to 15%.
Christians, more than anyone else, have contributed to the welfare and protection of children
Arguably, childhood was a Victorian invention. Prior to the Victorians, children were seen as "little adults" and in need of few more protections than you'd give any small person. I do not know what Christianity had to do with coming to see children and childhood as in a special category all by themselves. I'd be interested in hearing the story of that.
No other group in human history has fought the slave trade more than Christians have
Here, you really must be careful. Underlying the slave trade was the creation around 1500 or so of an ideology that Africans were decisively inferior to other peoples. That ideology was rationalized in biblical terms. So, while Christianity did not inspired it, Christianity came to rationalize it. Make of that what you will.
No other single group in human history have contributed more to the cause of charity than Christians
Charity, maybe. But charity alone will never solve the problems it tries to ameliorate. Only a socially conscience people most likely employing government means can do that. And for that kind and degree of social conscience, we must thank the Jews, more than anyone else.
Beyond that, it seems to me highly arguable that Islam has done as much or more in terms of charity as Christianity.
