definately (not five fingers)

what if i take off my hands from pocket and its having 4 fingers...??
well..i wonder how the nature would adapt the change in itself,if (mass of proton was 1.57 not 1.667(approx)
if we could see thing not in a flash,i mean not in 1/c seconds(which is too fast) but a bit slow..i mean that (say the hall is 640 m long and speed of light is 320 m/s,so their would be a natural delay of 2 seconds to see the person standing at the other corner) actually we dont notice that whatever we see is 1/c seconds older...it would have been something so funny if  c=1000m/s(say) and not 3*10^8 m/s....
how things would appear??aaah...a complete drama....
is everything planned that for so and so species on so so planet (h and o combined in 2:1 ratio will do the job)??
i mean why the creator will show extra love for 2:1???
i just want to have this answer.... is every number beauty in itself.....what if golden ratio was not 1.68??how things would have changed????
