Science for me, is the proof other people need. When you know inside, you just know. People can throw anything they want at you, and about your beliefs, but no matter what you can still smile and have that amazing sense of knowing, that only comes from looking inside. The truth is inside, not outside. You can change belief systems at any point to try it out, but there is always the 'real' truth, that which never goes away. Because it has always been there, you just need to connect to it, when you do, you will know.
