One we don't have the resources to get out that far but money isn't the problem its the time to get there. Two religion has no control over what we decide to do for even in the bible it states we were left to fend for our own free will. Three the unknown is scary because we don't understand it and that's normal but remember science is humankind's best guess with trial and error. Please remember in this world anything is capable of happening so you'd have to assume everything may or may not be the actual truth. So in this touchy subject you can't be focused on just one idea but become open minded to all that exists. Researching just one thing because you have come to be something you know is the most common setup for failure. Einstein once said if you cannot easily explain something perhaps you yourself have not come to understand it either.
