I don't agree with you; one must believe in Him, in my opinion. Science is not be all and end all of life.
What do you think obligates people to believe in any given deity if not for evidence? People don't usually accept claims without evidence, so how is it fair to expect them to accept universal metaphysical claims in the absence of clear supporting evidence?
As for the 'randomness' argument — which has been brought up again in this thread — I believe I have answered this not long ago, so I'll just repost my counter-argument:
I don't think that all structures that we perceive to be 'complex' necessitate design. It may be intuitive to think so, but I don't believe that it has to be the case all the time.
As an example of that, imagine the placement of pebbles on a beach. For the sake of argument, let's pick an arbitrary number of pebbles to work with: 124,000.
If the beach had enough space for
exactly 124,000 pebbles and the sea waves moved them so that each pebble ended up in a certain location, the probability that a single pebble end up in its given place is 1/124,000. At first glance, this may seem like a very improbable event that was influenced by an outside force(s) (or designed, in the case of the scenario in the OP), but the sea waves' motion, along with other factors that might have led to such placement of pebbles, is random. The sea isn't sapient or even sentient, so such placement is entirely unplanned.
So while the probability that each pebble lay in its specific location is 1/124,000, the probability that it will lay somewhere on the beach once it is on solid ground is 1. It will certainly end up at a point there if it reaches the shore, which means that an event perceived to be very unlikely (e.g. with a 1/124,000 chance of occurring) is certain to happen if enough coincidences take place — such as the pebbles merely reaching the shore.
I believe it is possible to think of certain occurrences in the universe the same way: it might seem counter-intuitive for them to happen spontaneously or in a random manner, but a totality of said improbable events is certain to happen, much like the placement of pebbles on the beach as in the example above.
