Science, as we define it, is simply the study of the universe as WE perceive it in terms of physical, biological and chemical phenomena etc. Our perceptions, however, are limited to the four dimensional components that constitute space-time. This would decree a somewhat limited knowledge and perception of the ‘bigger picture.’ God is not subject to such restrictions and, consequently, examination by such methods would prove fruitless. An example of our restricted insight, for me, was demonstrated by Professor Stephen Hawking in his latest publication, one of the greatest thinkers of our time appears to be incapable of envisaging a dimension which exists ‘independently’ of space-time. To reiterate the comments proffered by Alberti, you cannot use science to prove omnipotence, omniscience or omnipresence. However, science and faith in God are certainly NOT mutually exclusive.
