Who created the Bubble?

Could you please provide some insights into the question, "Who created the Bubble?" I'm interested in understanding who or what entities might be responsible for the emergence of this economic phenomenon. Could it be attributed to a specific individual, a group of investors, or perhaps broader market forces? What factors contributed to the formation of the Bubble, and how did these factors interact with each other? Additionally, is there any historical precedent for similar bubbles, and what lessons can we learn from those instances? I'm eager to gain a deeper understanding of this complex topic.
