What scientific evidence? At the base of each mind theres a source of awareness, consciousness, then theres the mind, a creation of the brain as a result from identifying itself in a physical world, where everything is separate, your brain develops a sense of self, and the self is selfish, it wants to satisfy itself, obviously. That's your ego, your ego either wants security or happiness, or is perhaps afraid of judgement of others, or perhaps criticizes others by comparing itself and reassuring itself of its significance to gain even more self worth. Whatever you do in this life, at least for most people, is to look for permanent satisfaction of your ego, yourself by impermanent means and you don't know that you're doing it. Unless you genuinely start to question the nature of reality and yourself, then you will never awaken from being driven by your ego. You wont find the answer in philosophy or science or religion, these are just frozen concepts of an idea that cant be grasped by the mind. You need to contemplate deeply and realize that your feelings and your emotions and your thoughts are based on external factors and don't exist in their own right, they are simply a side effect of interpreting a physical reality. You must realize that all you really are is consciousness, simply existing, infinite, beyond space and time, everlasting, knowing itself by direct experience as its the source of every single element of our world. Consciousness is God as we call it, and we are part of it and its part of everything. What this existence means is simply consciousness experiencing itself. We are on a ride, its just a ride.
