In this video, Elizabeth April explores the concept of why humans have to experience both light and dark energies on Earth. They discuss the idea that humans are hybrids with different interdimensional DNAs, and by experiencing both polarities, they activate different strands of DNA within themselves. This process allows humans to reach a point where they have experienced everything as a hybrid and can then choose their state of being. The fifth dimension is described not as a state of being, but as the ability to make a choice based on ones experiences. The video concludes by highlighting the uniqueness and challenge of the human experience on Earth.
