There are a lot of evidences that they have already visited the Earth... The science community does not recognise it, but there are lots of ruins of old buildings that can only be built with laser tools, electric saws... Technology way too advanced for the time when they were built...
Also, old civilizations wrote about them, describing them as 'gods', star visitors (that's what they were to them, what better way to describe it?)... There are a lot of evidences that support the theory of ancient ETs and they guided the ancient civilizations

I think that extraterrestrial life is definitely a possibility. The most basic argument I can make for that it hasn't been proved otherwise and the data we can collect regarding life in other parts of the universe is rather limited. Given that the identified conditions for life can be met, and that we have not been able to define life to a degree of certainty to begin with, the possibility of extraterrestrial life is very real. However, as for them having come to Earth, I'm not sure there is enough evidence to corroborate that.

Define life... Experiences made by the Viking probes in Mars found gas methane in the atmosphere, only when it is summer on the planet... That means two things:
- methane is liberated by organic life and volcanoes... But if it was with volcanoes, there would be also sulfur dioxide (by the lava)... That was never found... So, something organic created it
- that is also proved by only finding it in the summer... When temperatures are warmer... We all know that the cold freezes all microrganisms, like a standby... When it gets warmer, they start "working" again... And, geology do not chose seasons, so volcanoes aren't the ones to blame...
Another detail: atmospheric methane is very instable, UV light and other chemical reactions destroy it, so if it was found, it means there is a constant source of it...
So, we know there is something organic inside the marcian soil... Probably bacteria, like the ones found deeply in our oceans and such, called extremophiles... But that's not the life definition you want, I think... But life nevertheless... And it means that life is very resistant... And that may say that life is very common in the universe... And we may be all extraterrestrials... Who knows? Rocks from Mars fell here, the most known is the ALH84001, that fell here around 13000 years ago, and they found bacteria there and they proved those had millions of years old...
So we might be sons of ETs... That's called panspermia...
The problem is that we are use to believe we are special in the Universe...

No I agree that there is life in the universe other than on Earth, that is something  I am not debating at all. However, regarding extraterrestrials coming to earth, I am skeptical. The methane argument, without sulphur dioxide was torn down because the required amount of oxygen to facilitate the conversion of metal sulphides from Mars' core to oxides was not present. So it is still very possible that Mars does not have any sign of organic carbon based growth.

The reasoning for the eruptions in summer was based simply on pressure development. Volcanic eruptions in active volcanoes happens periodically. And finally, and most importantly, Mars is self-sterilizing. They believe the combination of solar ultraviolet radiation that saturates the surface, the extreme dryness of the soil and the oxidizing nature of the soil chemistry prevent the formation of living organisms in the Martian soil.

Methane is destroyed by UV rays, true, but atmospheric methane was found due to the self-fertilizing soil structure, that leads to a methane cycle much more rapid than that on Earth.

I'm not going to comment on panspermia. And I am by no respect saying that we are special in the universe on the basis of the formation of life here. It is most definetely a possibility that many planets have life forms that have not been discovered so far. In the Solar System itself, there are promising leads, no doubt, but they have been carefully debunked in some sense, especially in the case of Mars.

Explain the Nazca lines...
and specially the Puma Punku ruins, how did they build it? how did they cut those rocks with such precision?

and explain to me, why doing this?


I won't even refer the pyramids (in all continents), the Easter Island, the Gobekli Tepe in Turkey, etc...

[Ater Nox]

There are a lot of really old rocks that have been carved to be straight, I don't think that means aliens

Why bind someone's head to make them have a pointy skull? Human's are weird af. They used to break and bind woman's feet in China, and today people decorate themselves by piercing themselves with metal or injecting ink into their skin.

I agree that the odds are aliens exist somewhere, but I don't see any conclusive evidence they've been to visit us.

[Tuga Nation's Dragon]

Rocks carved to be straight, but with a precision of a fraction of an inch? A laser precision before the age of iron? That's difficult... And those rocks all fit on each others... They can even make hinges when together...
Or they knew way more than we think it was possible and all History is wrong or someone or something did that...

Which rocks are you talking about, if I may?

Pyramids have a quite well defined history if I'm not mistaken, considering the labour required to build them, the feeding and nourishment conditions of humans at that time and most importantly, their organization system that allowed for such a system to be built.

Misinterpreted history is definitely an option. Historically 100% of the best libraries of any civilization have burned down. It is possible that the numerous burned manuscripts had some inking or understanding of nature and natural forces better than we did. But extraterrestrials, I'd say great conjectures, but no evidence whatsoever.

See the rocks of Puma Punku

[Ater Nox]

So far no one thinks aliens do not exist anywhere. I think Aersoldorf might be in that camp, but I can't remember.

[Aersoldorf]

True

[Tuga Nation's Dragon]

By the principle of mediocrity, we are not special, so they are out there somewhere

[Jabberwocky]

Not only are there extraterrestrials, we are them. I know; a ghost told me.

[Dragon Blade]

The universe is nearly infinite in possibilities and there’s a really good chance that sentient life lives somewhere among the stars.

[Jabberwocky]

As a reporter from The Mad Surfer, I ask you if there is sentient life on Earth?
