No, because earth would have been in a completely different location in spacetime.
Obviously, but that's not the theoretical discussion happening here.

You wouldn't see "yourself" unless you happen to be looking at a specific spot where a 200-year-ago version of a person (or their ancestors' environment) was visible in the reflection. The mirror reflects the entire illuminated side of Earth (or whatever portion faces it), so it's like viewing a distant image of the whole planet from that era.
And in order to have sufficient resolution to see a person you'd need an unimaginably large lens.

OT does not disappoint.

microscope is the proper word - you be looking at an image from 200 light years away - even stars appear to be nothing more than dots at that distance.
of course it is all a thought experiment - impossible to arrange a constant distance and fixed relative angles across 200 light years of space.

Your last erection would still be long time gone.

If something 65 million light years away was looking in on us they would see dinosaurs

Not with computers.

Oh frick.
We may not be able to travel physically in time, but maybe we can view the past with mirrors.

Yes, if you're still standing there in 200 years.

Only if you got lucky enough to find a naturally occurring mirror that happened to be aligned such that it reflected light from Earth’s exact past position to its exact future position.
If you built a new mirror, say some sort of spacecraft, and launched it, then the absolute best case scenario would be that someone in the future sees Earth in the state that it was in when you launched the mirror. You could never see anything further back than that, because your mirror can’t travel away from Earth faster than light.
It would effectively be the same thing as launching a spacecraft with a camera pointed at Earth, and having it constantly transmit images back to us. Assuming the transmitter is powerful enough, you’ll eventually see images of the “past” but they will still be images from after you launched the camera.

You would see something like this:

Which would be nothing because Earth was in a different location 200 years ago.
