Substitutionary Atonement! WTF?

Actually we've improved quite a bit over a long time. If anything has been holding us back, it's religions such as christianity...

I've only just found this: badnewsaboutchristianity
And oh boy, Christianity gets kicked twice around the equator and thrice over the poles.

Christianity brought the Dark Ages to Europe, a period when scientific endeavour was abandoned and learning of all kinds was rooted out and destroyed. With the exception of military technology, the Church was to oppose advances in virtually every scientific discipline for many hundreds of years. Philosophers were persecuted and their books burned. Such was the persecution that men of learning were driven to destroy their own libraries rather than risk a volume being seen by a Christian informer. Efforts were made to destroy evidence of Greek successes. We can never know how much was lost forever. Some Greek learning was preserved because Christian heretics, notably Nestorians, took it east with them when they fled the wrath of the orthodox Church. These refugees flourished under Zoroastrian and Muslim rulers in centres like Damascus, Cairo, Baghdad and Gondeshapur in Persia. There they translated surviving works into Syriac, Hebrew and Arabic.
