Dispelling superstition

Conspiracies and theories
They promulgate to death
Always form a series
Of concepts so far-fetched

But the answer is more humble
There are no aliens
The theory takes a tumble
Because they're all simians

What are the chances of an alien like that?
Their anatomy suggest they're humanoid, minus fat
On other planets the atmosphere would kill
The time it would take to get here
Is something they could never fulfil

It would take eternity
Travelling this distance
Across the universe
And even the fraternity
Of beings wouldn't see us
They'd die before getting close

Even if longevity
Is much higher for them
They don't have a cure for death
The journey would take centuries
To their death they'd be condemned

This is all because they came back here before their birth
They are just humans from our future on this earth
They have evolved beyond we evolved from early man
They are part of an elite a struggling future clan

Can't you see what you're buying into? It's marketed as truth
They call it "The Alien!", so you will buy their magazine
Time travel theory is likely, as opposed to "aliens"
Their world in the future is so much more feasible

Like Brave New World, infected clones.
The sense unfolds, compare their bones with homo sapiens
We're so alike. There's no "alien" you know it's right

Time travel is more feasible than humanoid galaxian voyagers
Think about blackholes and wormholes
We're going to be time-dimension warriors

Their heads are substantial because they've evolved
(Perhaps these thoughts have already been thought)
They use the other 80% of our brain
They've learned new ways of overcoming stress and pain

People want to believe that we're "not alone"
But surely the idea of time-travel clones
Is just as enthralling as life elsewhere
One day they'll discover them and then they'll care*

Because of their large brains they communicate
Without using their mouths they are telepathic
And no need to defecate because they take pills which
Satisfy all their needs without the waste products we have

UFOs: they disappear
Because they're shifting dimensions for a moment
To avoid changing their future world

Their eyes glazed over because the atmosphere's too gaseous
This is why their nostrils are so small to guard their lungs
Their skin discoloured because they lack oxygen and bloodflow
And their circulation is restricted by pollution

The reason they come back in time
Is because they're running out
Of things they use too much
Like raw materials, air
And organ donors, no doubt
They're running out of luck

Perhaps they have no record
Or history of our race
Was it destroyed by fire?
And they almost got wiped out
By pollution or plagues

Abductions of modern humans rarely occur
Because they don't like to interfere with their past
It could have a devastating effect on their lives
If they tamper too much with us, their civilisation won't last
