An alien race millions of light years away, manages to warp thru space at faster than light speeds, avoid asteroids, the pull of other planets, escape the effects of solar radiation, manage to feed and hydrate their crew, decelerate and enter our atmosphere after performing a navigational miracle to get here, avoid burning up on entry, and just before they get close to the ground they need to turn on bright lights to see where they are going?
Doesn't anyone find the problem with this arrival profile of aliens?
