[Lego] Do all the lego series/theme take place in the same universe?

Was thinking about this recently. For instance in the lego racers and Racers-2, the city/town,space (UFO, life on mars), artic, johnny thunder, and racers Xalax themes appear; while in "clutch powers" movie, the city, castle, space (mars mission, space police), agents, powerminers, and other themes appear. In the legoland game the scientist also gets teleported to Planet-U from rock raiders.

Would this mean that all lego series/themes (excluding licensed ones) are based in the same universe and that the only difference is that there in different time periods or planets (ie rock raiders happens many years after the events of power miners)?

Or are there are few lego universes since there would still be some inconsistencies such as Life on mars and mars mission.

What are your thoughts? Is it the same universe spread out throughout time and space, or multiple universes?

It's clear that the vast majority of original Lego themes take place in the same continuity, whether through explicit connections (a Power Miners character appearing in an Atlantis set, e.g.) or easter-egg references (the Classic Space logo, Octan). It's possible that Life On Mars and Mars Mission are merely different eras and regions of Mars exploration, each encountering a different native species.

The only themes that might be difficult to reconcile with this notion are those that have specific years, namely Ice Planet 2002 and Dino 2010, since, uh... we didn't go to an ice planet in 2002 or get overrun by Dinosaurs in 2010. Such massive shifts in society would have been reflected in Lego City sets (which run parallel to our own reality in terms of culture, technology, and chronology).
