I'd think the worse case scenario would be sentient machines who don't need no stinking life forms, and who respect them even less.
But I also think it highly improbable that any aliens that came here would be able logistically to come here in force. Then again, perhaps all they
need is one robust spacecraft, along with a data bank of describing every aspect of their race and the flora and fauna of their planet, with which
they could go about reconstituting all the organic matter on this planet in their planet's image -- not a pretty picture for us or terrestrial
microbes for that matter.
Ya - I have a hard time trying to get inside the confined space of the OP's head.
Sentient machines is almost certainly the most likely alien beings that we encounter. Possibly they were originally organic, and perhaps are able to
switch between machines and organic forms at will - creating the organic form out of handy material - like a transporter, but just using raw data to
create a new body.
However sentient machines are more likely to be far more humane than us, people often think of machines as not having emotions - but that is purely
because our current machines are so low tech. Emotions are very useful for survival, and advanced machines would definitely make use of that
improvement - but they would likely have absolute control over their emotions.
You suggest the ET's might not be able to arrive in force, I find that likely only in the most primitive ET's. Advanced species could simply move
our earth into the orbit of their distant star to check us out, or bring one of their suitable worlds into out solar system.
They would be able to take over human bodies via remote control at will using signals attuned to our mental facilities. They could just turn us all
into slaves with a flick of a switch.
If they just wanted to get rid of us they could introduce virus and kill us all before we even knew they existed.
It depends on how advanced they were - but looking at the numbers I'd say if we are visited its most likely they will be thousands of years more
advanced than us, probably tens of thousands. The very advanced species we might never encounter because they simply don't exist inside physical
If an alien attack appeared, it is likely the entire thing only occurs in our minds as they take control and show us possible events. Or if they
appear and we fight hem, that the bodies or machines that we kill are just replicated and can be replaced an infinite number of times - they would
only be fighting this kind of battle to allow us to learn, not to defeat us.
The OP has a massive failure of imagination and an incredible hubris - if someone who can come here means us harm, then its almost certain that we
will have no hope.
Intelligent species are almost all likely to be drawn from predators if they are organic, inorganic ET's may just be terraforming drones, but they
will probably be equipped to deal with anything we could throw at them. So biological ET's are likely to know the arts of war, and have advanced
If they are true sentient inorganics then any contact with them would be of the order of ants to humans, they could understand us and communicate -
and they might present themselves as very normal and interesting humans - but that would be like us playing fetch with a dog - the dog thinks we are
the pack leader, but our social organization is so far above the dogs that we just humor the animals because they are loyal and without guile.
Of course then we can consider beings who exist outside of space time, they would simply be gods to us - we could not effect them in any way and only
detect them if they decided to manifest themselves.
Considering that the universe is supposedly 14 billion years old - and that a planet can produce complex life only after about 3.5 billion years, and
our current 'advanced' technology has existed for less than 100 years, the chances of meeting an alien species who are within our range of
technologies, give or take 100 years would be as follows;
14 - 3.5 = 10.5 billion year range of possible age of intelligent ET.
100 years variation /10,500,000,000 possible age of ET civilization = 0.0000001% chance
We are not going to run into some backyard hick ET, they are going to be far more advanced than us - its just math.
