Sacred silence?

Most religions indicate that creation began with sound-OM in Hinduism; in the beginning was the “word” in Bible, and the big bang as per quantum physics
Well, what did happen before the big bang? If the big bang was the beginning of time itself, what happened before the big bang…Was it the timeless sacred silence, the eternity, infinite?
Why there is a universe, time and life etc?
Perhaps science cannot answer such questions. Science is good at telling us how, but not so good on the why.
Aum -Om- Aboun-word
For the Hindus and Buddhists, Om is the primordial sound, the first breath of creation, the vibration that ensures existence. Om (Hindu) and Aboun (Jewish) sign signifies God, Creation, & the One-ness of all creation.
Primordial Sounds are the basic, most essential sounds of nature. These Primordial Sounds are used in meditation. They are chosen on the basis of Vedic mathematics which determines a specific sound or vibration of the Universe.
Don’t think too much like Stephen Hawkins…Just meditate on these primordial sound…You will be fine..
