The first problem is that "modern materialistic science" has everyone buffooned.
We are taught to believe in actions - reactions
We are taught that actions are followed by consequences.
The universe doesn't work this way.
The future paints the present upon the backdrop of the past.
All of the happenings happen because of the future we are drawing towards ourselves. It doesn't matter one iota which decision you make, it will lead towards that future.
So, if you wish to stop a certain future, you need to realize what in you is attracting it, and then change that, and start attracting a new future. This usually requires a great deal of introspection. To know Thyself.
Like a person who didn't get love as a child will continue to attract people that don't give them love (they are standoffish, or non-communicative, or not available...). They will continue this cycle, bring about a similar circumstance until they heal this wound within themselves.
One of the most important things we as a civilization need to do is start learning to see the future, to see what future we are attracting so that we can change it if we do not like where it leads.
There are a great deal of psychics. Well, because everyone is psychic, its just very few develop those skills.
