God is both Alpha and Omega.
Evading quantum barrier to time travel
by I. Peterson, Science News (11 April 1998)
In a paper submitted for publication, Li and Gott
explore the question of whether anything in the
laws of physics would prevent the universe from
creating itself. "The universe wasn't made out of
nothing," Gott suggests. "It arose out of
something, and that something was itself. To do
that, the trick you need is time travel."
Li and Gott speculate that a universe undergoing
the rapid early expansion known as inflation could
give rise to baby universes, one of which (by
means of a closed timelike curve) would turn out
to be the original universe.
As they did for Misner space, the two physicists
found a self-consistent vacuum state,
demonstrating that closed time loops can occur
under inflationary conditions in certain space-
times. Hence, the researchers say, "the laws of
physics may allow the universe to be its own
mother." ...

Can the Universe Create Itself?
Authors: J. Richard Gott, III, Li-Xin Li

Journal-ref: Phys.Rev. D58 (1998) 023501
The question of first-cause has troubled
philosophers and cosmologists alike. Now that it
is apparent that our universe began in a Big Bang
explosion, the question of what happened before
the Big Bang arises. Inflation seems like a very
promising answer, but as Borde and Vilenkin have
shown, the inflationary state preceding the Big
Bang must have had a beginning also. Ultimately,
the difficult question seems to be how to make
something out of nothing. This paper explores the
idea that this is the wrong question --- that that
is not how the Universe got here. Instead, we
explore the idea of whether there is anything in
the laws of physics that would prevent the
Universe from creating itself. Because spacetimes
can be curved and multiply connected, general
relativity allows for the possibility of closed
timelike curves (CTCs). Thus, tracing backwards in
time through the original inflationary state we
may eventually encounter a region of CTCs giving
no first-cause. This region of CTCs, may well be
over by now (being bounded toward the future by a
Cauchy horizon). We illustrate that such models --
- with CTCs --- are not necessarily inconsistent
by demonstrating self-consistent vacuums for
Misner space and a multiply connected de Sitter
space in which the renormalized energy-momentum
tensor does not diverge as one approaches the
Cauchy horizon and solves Einstein's equations. We
show such a Universe can be classically stable and
self-consistent if and only if the potentials are
retarded, giving a natural explanation of the
arrow of time. Some specific scenarios (out of
many possible ones) for this type of model are
described. For example: an inflationary universe
gives rise to baby universes, one of which turns
out to be itself. Interestingly, the laws of
physics may allow the Universe to be its own
mother.

Robyn,
This section is for creationists only. In addition, even in spite of the fact that you aren't a creationist the article you quoted from asserts that the universe is self-created as opposed to being created by a personal God.
