The Vulnerability of Humans in regards to offworld species

I think a good way to put it is if you observe what happened on the Hawaiian Islands in regard to invasive species mostly brought by Early ships like Captain Cook came on and after. These invasive species like Rats and then the mongoose which was brought in from India decimated local tropical bird populations. Similar things are still taking place on Hawaii.

Similarly, because offworlders have always been coming to Earth (in fact likely we are a cross breed as humans of offworlders and apes). The reason this is likely true is that humans are the only species on earth that has speech and the ability to speak in languages. Where did this trait come from otherwise? No ape or chimpanzee is capable of speech. So, where did this trait arrive from? My theory is that it arrived from off planet during either genetic engineering or interbreeding with humanoid alien species at some point. Then likely we became lesser than sort of like servants or slaves. But then since we bred faster than aliens we became a physical problem for them to survive because there became so many of us in relation to them.

So, our vulnerability to alien species mostly is we are not allowed (formally) to even recognize that aliens from other planets or from our deep future or past makes us incredibly vulnerable to those who travel both space and time. And they know this too. So, my thought is that our governments not wanting us to formally speak about these types of beings and situations only makes us 100s and 1000s of times more vulnerable to all these ongoing events for literally ever since Earth existed.

Also, another thought we should be thinking is this: We were allowed as humans to develop the cultures we developed. Why is this and for what purpose or purposes was this allowed by extra terrestrials? This might be an important question to consider as well.

I was having a conversation with my wife about this and she was trying to tell me about the potential different motivations of extra-terrestrials versus humans on earth. My approach was more pragmatic and I compared our recent (last 10 years) of actions as the United States into Iraq and Afghanistan and I compared that directly to the interferences of Aliens ongoing here on earth.

From an alien point of view (both through space i.e. other planets and through time 'future earth or past earth visits to the present from earth or beyond) Earth would be seen like a city in space and one of many. So, likely they wouldn't see space as we do at all. It would just be like going from Chicago to Los Angeles by plane. When you travel through both time and space simultaneously all visits are instantaneous sort of almost like walking out your front door and finding yourself in another city, country or planet.
