Not only is the earth never in the same spot, the solar system it's never in the same spot either. Even our galaxy is moving.

so would it be accurate to say that if one were to take a frame of reference on a large scale, say, the absolute centre of the universe (I know, but bear with me on this one), it's also fairly impossible to travel back in space as well as time, seeing as by the time it takes you to take a step back to your original position, the earth has already moved enough that you are no longer there relative to your reference?

I'm not sure "an absolute reference frame" exists. But, in your scenario they'd have to lead the shot so to speak. And jump in behind where they want to be.

And also any future position may be dependent on many variables that might be different each jump. If you were to go back in the past, the future location may be off greatly; just by going back may have altered the future location, insert multiverse theory etc

You'd almost need to somehow communicate back to or do some kind of survey or probe of the target space time coordinates and confirm somehow they are what/where you think they are, and lock in to them before actually doing the jump. Sounds impossible lol

That's what the Spice is for!
