In science we have the knowledge becoming finer and finer. From large objects to molecules to atoms to electrons, protons, neutrons to leptons, mesons, quarks, bosons etc. to tiny strings. At this point, in my knowledge the presence of strings is not experimentally verified. However, even if it is verified, another question would come up as to from where are these strings coming up. As existing questions are answered, new questions come up without answers.

Finding ultimate truth via science looks like a mirage, the closer we go, farther it recedes.​​

The final answer that can be found via looking inwards is that everything is made up of consciousness. Now, if somebody asks how did consciousness come into existence, the answer is that only consciousness can ask this question as an inert thing cannot ask this question. So, the questioner himself is consciousness and the question is also taking place in consciousness. There is no question of “when” as there is nothing else but consciousness.
