Hey, I agree with hoby. Do you really think that we are alone in this vast universe?
Remember in school when they taught us that "Europeans" though the world was flat and that you will fall out of the Earth at a certain point? Well, they were wrong. Now we know that the Earth is round.
Right now, if you think about it, we are now branching out slowly into what is outside our planet. I think the reason why extra terrestrials have not publicly announced themselves is because there is too much racism, hate, and issues among us. We have evolved into a materialistic world and have slowly drifted away from mother Earth and spirituality.
I believe that with high technology there also needs to be advance spirituality. There needs to be a balance. High technology comes with spirituality. Psychologically, physically, we are still evolving. They are waiting for and helping us get to where we need to be. We tend to overlook the simplicity of things. Love, forgiveness, sincerity, etc. We need to focus on finding our inner peace and then that will fix how we interact with each other.
Also, why do you think that the indigenous people all over the world believed in chakras? Why is that North and South American indigenous peoples built pyramids like they did in Africa? Why is that certain indigenous tribes of Mexico speak an African dialect?
There is a lot of mysterious to be solved and a lot of the history was erased because of Christian Europeans doing their "missionaries". Europeans used religion and construction of race to justify their exploitation of indigenous people and to defend their race because African genes are stronger. Well, I hope that gives you a lot to think about.
