Except that's still just wanting to be gullible and believe it's not a complete lie, even if you have to make up what happened there, in the absence of any evidence that it is so. In fact, if you look at it rationally:
1. Such nova, or a star clustering, and even more so a comet, would not point anyone at a particular house, nor even at Bethlehem, nor for that matter even at Judaea.
Even with modern software you'd get a very fuzzy spot of what's the place where Earth's surface is intersected by a line between that star and the centre of the Earth, i.e., what's "under" it. And even then that point would move at bullet speed (no, literally) over the Earth. In the time it took to come there from Iran, that position would have drawn a circle or more accurately a tight spiral all around the world. The very notion of a star showing you a position even for an hour is nonsense, as in an hour it would have moved the whole width of a timezone, and really, look on the map how big that is.
But the ancients could do no such thing anyway.
2. A planetary alignment even more so, as that would be in the solar system's plane. The Earth's axial tilt is only about 23 degrees. Bethlehem is just a little over 31 degrees north. You do the maths. There's no frikken way that such an alignment EVER was directly overhead in Bethlehem, or for that matter anywhere in Israel at all.
Just because some religious twits want an actual sign in the sky making the story true, doesn't and can't override the fact that it's mathematically impossible for some kinds of a sign to happen over that place.
3. The Magi which had the Mesopotamian tradition of astronomy going back 3000 years at that point, would already know that ALL stars rise in the east and set in the west. You know, because of the Earth's rotation, or as they'd think at the time, the firmament's rotation. It would be illogical for them to go east just because a star rose in the east. Unlike dumbasses like Matthew, they'd know that a star doesn't just stay hovering over a point in the east.
4. The Persians, just like the Greeks, were already able to do some adequately accurate plotting of the planets' positions in the sky. See the Antikythera mechanism dating to about 100 BCE. Ok, that's the Greeks, but the Persians had all that knowledge of the skies too. A planetary alignment would not come as a cosmic surprise to either, much less some miracle that marks the coming of the (different religion's) messiah. Which brings me to...
5. The Magi, i.e., Zoroastrian priests would not have explained it as the birth of the Jewish messiah, nor come to worship him. That very notion is as silly as having a group of Christian astronomers go, "hey, look, that new star we found... that's the star of Mohammed, let's go to Mecca and convert!"
6. In fact, the whole episode is more easily explained as symbolic of their messiah expectations. What makes you think that a symbolic piece of fiction had to have a real star, or for that matter any cosmic event, as a backdrop. Why not just invent it too? Do you think Andoria or Qo'noS are a real planets because Star Trek has Andorians and respectively Klingons? Do you think some significant star alignment happened in 1925, just because The Call Of Cthulhu says R'lyeh rose on that year, and Cthulhu woke up (even if fairly briefly before hitting the snooze button and going back to nap another aeon

), and that can only happen "when the stars are right"?
7. There's the fact that if that coincided with Jesus's birth, well, we have the problem that each author places that in a different year. Whatever might have happened up there, it didn't happen in 6 AD (Luke) and 4 BC (Matthew) and 8 BC (Epiphanius) and 6 BC (modern harmonizations putting a 2 year gap or so between Jesus's birth and the slaughter of innocents) and so on. Especially tightly clustered planet alignments don't happen every 2 years or they'd be even more mundane things that totally don't warrant buying gifts and going looking for a Messiah.
8. We not only have the problem that the Magi followed the star as accurately as from Jerusalem to Bethlehem (and that's just too fine resolution for that age or even for today, especially since, again, it moves), but apparently followed a star in the EAST to guide them to a city to the SOUTH. Matthew generally doesn't seem to be an authority on celestial phenomena, but there you see he doesn't know geography either. And now we can add a geographical impossibility to the rest of the problems with taking that star episode seriously.
9. We have the same contradiction of being both significant and insignificant that generally plagues Jesus. Whatever is supposed to have happened in the sky is supposed to be significant enough that both the Persians and Jews take it as marking the beginning of the messianic age, i.e., doomsday. Yet no astronomer finds it worthy of any notice. Whether it was some alignment or a comet or whatever, it must have been a pretty unimpressive thing. We find mentions of all sorts of other comets and signs being ascribed significance, but that one? Nope, nobody seems to write about that one as marking anything.
10. By contrast oral traditions are what uneducated, illiterate people did. An astronomer finding something significant about such a cosmic event, see above, he'd just WRITE about it. So we're having some anonymous and unverifiable dumbasses (no, really, even Paul calls his believers stupid) who don't know jack about the sky tell us what happened up there, that all the astronomers somehow missed? Really? Do you actually think any of those were in a position to know if a planet grouping is any different from last year? Do you think some fishermen from Galilee actually tracked down star positions?
And generally, isn't that a bit on par with trusting some schizophrenic hillbilly that there actually was an UFO up there, although all the radars and airport control towers and the airforce somehow missed?
11. Matthew is just not a reliable source on astronomy, or for that matter a source on anything true. We also see him inventing an impossible sun eclipse that's both impossibly long, and plain old impossible because it's on a full moon, for example. Does that sound to you like the kind of guy you'd take astronomy evidence from?
Not to mention such stuff as the great zombie invasion of Jerusalem, and all sorts of nonsense. He just doesn't seem concerned with what's verifiable, and has no problem writing down stuff that anyone could tell him never happened.
Etc.
