The most popular idea about aliens is that they look very different compared to humans. In reality, some aliens look like humans, and some of them even walk on our streets without people knowing their identity. Some of them don't see themselves as aliens, they see themselves as humans living outside Earth, without restrictions to knowledge, technology, and spirituality. Some of them are very advanced, and they are just light. Others have physical bodies, they eat, drink and have other needs like humans do. They share with us their daily life, their knowledge, their spirituality, and how we can learn from them.
