Those answers are already here in the internet, people are already living by that info, and are the most loving people I have ever met, not perfect and know they never will be, but not scared as a lot of dumbfucks here. Ask big questions and you will recieve big answers. Start grasping the idea of extraterrestrial life, for most it will sink in about a year or two. Even human history is much more than most can even imagine right now.
Yes, "aliens" do exist, frendly, hostile and neutral.
Yes, God exists, but is not an entity, is the source of all that is.
Death is a concept of our limited physical perceptions, specially our perception of time, but it isn't linear, in reality it does not exist, you realize this once you "die", because our consciousness, our soul, is inmortal, it exists beyond time-space.
To much for you to grasp?
This is only the beginning of an endless journey of learning.
