Although we will see specifically the Christian version of these beings, angels are an object of study and admiration in many cultures and religions around the world. In their variant recorded in the Holy Bible, these creatures are described as beings of extreme power and strength, responsible for performing tasks entrusted by God to fulfill His divine will.
It is true that for skeptics, these stories are hard to believe. But remember that the books of the Bible were written in ancient times, when knowledge about universal phenomena was very limited. So if we look for solid, logical explanations of the angelic accounts and compare them with scientific and empirical discoveries, the resulting conclusion might surprise us. In this list, we will see that, in fact, angels could be actual life-forms living out there, right now, beyond our current knowledge.
