As I saw yesterday, science obviously cannot answer all the questions because we as humans do not follow a set of codes or programmed instructions..we have flaws, high and low moments and the likes of them. Humans cant be blamed for seeing a scientific book of facts as "bleak" because like everything in life. Its easy to know stuff but a lot hard to do what you know. Thats why we search for purpose and motivation everyday. Some find it in God, others find it in people. Some even find it in science. But thats just what makes us human- our ever seemingly complicated natures. Like you said sir, the best way is to create a balance. Well not everyone is able to do this. But I think we should all try. Cheers!!
