"At the same time" is an idiom that means "at the same moment" or " simultaneously." It refers to a situation where two or more things happen at the exact same time.
The idiom "at the same time" dates back to Middle English and has been used in various contexts throughout history. Its literal meaning is "at the same moment," but its figurative meaning has evolved over time to refer to a situation where two or more things happen at the same time. The idiom may have roots in the early Christian tradition of baptism by immersion, where the candidate was submerged in water and then brought back up at the same time as Jesus was resurrected.
