When humans wanted to first fly to space how did we know that we needed space suits to survive?

Simple experience. First, humans have long known that, at very high altitudes, we have a harder time breathing; therefore, oxygen equipment would be needed. We also know that extremely low pressure can be damaging to unprotected flesh, as a result of experiments, especially during the World War II era. Again, it was obvious that suits would be needed. Therefore, when planning for Space, which would see people exposed to extreme conditions, it was obvious that special equipment, such as suits, would be needed.
