Given context, I'm pretty sure what they are talking about is how far away from the Sun life has travelled. In that case, there are probably some deep Solar System probes with a few microbes clinging to them (assuming they survived that long).
The answer to the question of the OP has been that there has been no official test with Earth life (bacteria, insects or animals) with a distance from Earth further than the Moon.
The argument that Earth itself travels through space wouldn't be relevant since the consideration as basis for the question of the OP is that Earth life may be bound to a region around the Sun.
