Also could it be possible that the solar system we know today is the solar system that is left as a result of this 'planet' passing through it millions of years ago?

Not on the time scales oft associated with Nibiru. You have an easier time of recreating the solar system as is if you start off with another gas giant that gets expelled from the system after however many millions of years, but such simulations are still hypothetical without evidence.

If memory serves, that idea doesn't mention much about the inner solar system at all, so even if proponents want to jump onto it as evidence in support of their claims (bizarre, seeing as such a planet would be long gone never to return), it wouldn't exactly be the best of moves they've gone for.

As for this Annunaki theory,

The one about the civilised race mixing their own DNA into that of humans, for which we find absolutely no evidence? I think it's fascinating enough that we may just be the descendants of life that was hurled off an ancient Mars in an impact event before crashing down to the Earth after a journey through space. While 'farfetched', we've far more evidence of simple life not only surviving such conditions, but of simple life evolving into much more complex life millions of years down the line.

This would explain the annunaki and discount the 'massive object' in our solar system.

Assuming 'this' refers to solid evidence, sure. But 'this' refers to a tale woven by an economics student trying his hand at archeology, I'm not exactly sure that qualifies as an explanation…

So, even if there is that half a percent chance it DID actually exist, it still could not account for these supposed historical mentions of things like the wormwood star.

I think most supposed historical accounts of this 'object'….

Don't confuse "historical" with "mythological," wormwood being the latter.

The Hopi's with their 'Blue star katchina' were probably talking about the very rare event that dust & gasses in space can turn the moon blue.

The Hopi kachinas are completely and utterly warped by woo artists on the Internet. It's amusing how many cranks over the years have attributed multiple different objects to alleged kachina-related "prophecies." I encountered a weirdo on YouTube earlier this year convinced that the blue star kachina was Comet Elenin.

Only if you throw out everything we know about orbital mechanics.

As for this Annunaki theory, I'm still out on it to be honest with you.

To be honest, there's no theory to be out on. There's just a bunch of nonsense claims by disciples of a wannabe archaeologist/historian, none of which have any demonstrable basis in reality.

I don't believe in nibiru as anything beyond our neighbor, jupiter, but the theory that beings from somewhere else in the universe did come here and lay the building blocks for a civilised race, similar to themselves. I have never been selfish enough to think humans are the only life out there because the odds of that being wrong are infinate. Galaxies that hold millions of stars, millions & billions of galaxies & stars, and each star we can't see gives the chance of there being planets in orbit around it, and planets give you the chance of life.

Even if all of that is true, the odds of any particular alien civilizations A) consisting concurrently with any given Earth civilizations and B) contacting/visiting Earth remain astronomically low, the stuff of science fiction and woo. And, of course, there's the complete lack of any evidence even remotely suggesting that such a thing ever happened.

On the other hand, as noted above by Elliott, we have tons of evidence that life evolved right here on Earth, starting as simple, self-replicating chemicals and developing into numerous species suited to numerous terrestrial environments, over billions of years.

Perhaps Nibiru does exist, a few hundred lightyears away somewhere in the milky way or another galaxy somewhere different completely.

So you're just piling your own fiction on top of Sitchin's. That's not good thinking.

This would explain the annunaki and discount the 'massive object' in our solar system.

The Annunaki already have an ample explanation, found in ancient Sumerian mythology. They no more need explaining beyond that than do Zeus, Thor and Pangu.

/Perhaps Nibiru does exist, a few hundred lightyears away somewhere in the milky way or another galaxy somewhere different completely./

How could something from another galaxy come into our orbit?

You really need to educate yourself. What a ridiculous claim. Read less woo on the internut and actually look into basic astronomy. You're obviously bored by it since this post demonstrates how you probably never cared about astronomy until you heard about doomsday planets or alien greys. Seriously, it's annoying.

No it can't.
You have the same problems, as the planet would orbit the Sun.
It would disrupt that solar system change all orbits of both systems (time in a day an days in a year).
It would also be a single event never recurring.

Also 100 light years away means that it takes 100 years to get here at light-speed. It would minimal take 100 years to get here. This would never happen in your lifetime.
