Yes, you're absolutely correct in that significant advancements have been made outside Christian contexts. What Donnie was responding to was my original query, which had to do with the way Europe civilization advanced compared to civilizations in the Americas, which were also quite large and advanced in their own right. Still, the Europeans were far more advanced (relatively speaking) when they arrived in the New World in the 15th and 16th centuries. The practice of Christian proselytizing was one within the list of factors that Donnie proposed was a reason which may account for the discrepancies in advancements within parallel civilizations.
