Write your reply.

assistant: Yes, you are.  The fact that you can say what you just said just shows you
don't understand what Steady State is.  The original Steady State had
spontaneous creation in a vacuum feeding the expansion, and that's what
you've got.
This is dead wrong.  The expansion is uniform and the Universe contracts to a
point 10-20 GYA.  Your saying it doesn't has nothing to do with the evidence.
 And the charge of falsifying evidence is a serious one for which you'd
better have convincing evidence.
No, you're assuming lambda = zero.  If lambda is positive the expansion could
be accelerating.  The Big Bang theories do not need the expansion to be at
any particular rate.
Then the Universe would have an origin in time, wouldn't it?  Which is the
Big Bang.
You're just going to ignore the evidence?  Nice tactic.  That must make it
very convenient.
The COBE data is what the microwave background really is.  It's evidence for
a Big Bang.  There is no convincing rival explanation.  Your theory has to
have consequences for ALL the relevant evidence or it is itself an irrelevant
theory.
Huh?  What?  Come again?  What does uniformity of age have to do with value
of age?
Sure it does.  As I said, the Big Bang explains the distribution of elements.
 To displace the Big Bang you'll have to do quantitatively better.
Quantum fluctuation does NOT provide a steady stream of matter.  The whole
point about quantum fluctuation is that it doesn't last long enough to add to
the Universe in any measurable way.  Particle-antiparticle pairs are created
and immediately annihilate.  That CANNOT feed enough hydrogen into the system
to produce galaxies.
Your theory ignores pertinent information and gives an unnecessarily
complicated explanation.  If you want to say it's "heretical," meaning it's a
brave new Galileo-like challenge to the status quo, feel free.  But it also
appears to be wrong.
