Thank you for being upfront. :-)
One way to check into it might be to trace the current pattern of planetary orbits and see how far back in time we would have to travel to see all of the observable planets perfectly aligned, but even this excercise assumes too much, IMO. How long ago was it?
To be perfectly honest, I have no idea what you mean here.
What I mean is, take the uniformitarian approach to planetary orbits (at least the ones we currently know about). Trace their orbit backwards, assuming the orbits have been consistent for the past, oh, who-cares-how-many years-days-hours-minutes-newyorkminutes-seconds-nanoseconds, and see if there is any point at which they are all perfectly aligned. Just out of curioisty, how far back in time would that be?
