--Continous creation(steady-state)
basically tells us that the galaxies moved farther away from each
other, new galaxies were formed in between, out of matter that was
continually created. The universe would therfore look more or less
the same all the times and its desity would be roughly constant.
This projectedmodel suggests matter(in the form of hydrogen) is
always being created from nothing, and comes about in order to
counteract the delution of material which occurs as the galaxies
drift away from each other.
--A second explaination is called the osicilating model. This says
that the universe is like a spring, expanding and contracting,
repeating the cycle indefinitely. The basis of this theory is that
the universe is closed, that is, no new energy is being put into
it. The expansion of matter would reach a certain point and the
force of gravity would pull everything together b4 expanding again.
However, all evidences refutes this position; the universe is
clearly losing density with no sign that the persistant expansion
ever has or will reverse, and thus is not closed.
Dr.William L.Craig gives his conclusion about these two models
with:"Both fail to fit the facts of observational cosmology."
--At last, the big bang,.....Dr Edwin Hubble plotted the speeds of
the galaxies and confirmed that all galxies are moving apart from
us and one another.Theres the law: the farther away the galaxy is,
the faster it moves.
The implication of this is that at one time during 'creation' all
matter was packed inside a dense mass of temperature of trillions
of degrees. Scientists observed this phnomenon and infered that the
universe resembled a white fireball and "BANG"!! Then in 1965 two
physicians made a discovery that the earth was bathed in a faint
glow of radiation. This exact pattern follows the wave lenth of
what is expected in the Big Bang.
So skyfoo, sometimes Christians may know some atheism too 
or maybe more than you do
