The dinosaurs became extinct much more recently than that, around 67
million years ago.

But it blow away all of it, did it? Besides, weathering on Mars is
much less than on Earth. We ought to be able to see clear evidence
of the massive cratering from this epoch. We can't.

How? Presumably you are suggesting that the moon is a fragment of
the ex-planet, but how come it is spherical and in such a regular 
orbit? Also, why does the geology of the surface indicate that it
has been exposed to impacts with several periods of melting (the
maria) over a 4.6 billion year history?

And plate tectonics can't? How does your theory? Do you think a single
impulse (your event 160 million years ago) would provide enough
energy to continue to move the plates around even today? Which the
continuous motions of the Earth's mantle can't do?

I don't think you will find that at all. The Moon has a mass of 0.012
Earth masses; all the asteroids combined have 0.0004 Earth masses.
Ignoring significance ;) that's only 0.0124 Earth masses total, which
does NOT 'equal a good size terrestrial planet.'

Check your facts next time!
