I agree that scientifically it might have been a Big Bang but I interpret that as God commanding ‘Be’ and ‘It Is’. Please be patient with this quote but it portrays what I believe so you can understand where I’m coming from. Because I know Who Baha’u’llah is, I know this is true beyond any doubt.
It is in Our power, should We wish it, to enable a speck of floating dust to generate, in less than the twinkling of an eye, suns of infinite, of unimaginable splendour, to cause a dewdrop to develop into vast and numberless oceans, to infuse into every letter such a force as to empower it to unfold all the knowledge of past and future ages. This, in truth, is a matter simple of accomplishment. Such have been the evidences of My power from the beginning that hath no beginning until the end that hath no end. My creatures, however, have been oblivious of My power, have repudiated My sovereignty, and contended with Mine own Self, the All-Knowing, the All-Wise.
Bahá’u’lláh,
