Why aliens haven’t visited Earth yet​

Chip shortage.

 

[Mulefoot]

If life didn't spring up naturally some 4 billion years ago, how did occur.

I'm just saying there's zero evidence chemical evolution, there's also zero evidence for spontaneous generation and panspermia.

Turns out that life is a little more complicated than chemistry.

What game designer are you talking about, your not referring to magic, are you.

Could be magic.

 

[devildavid]

Not even sure what this means.

It's not that hard. Physical evidence never points to non physical causes, like a god.

There is not zero evidence, as you claim.

It certainly doesn't lead that life sprang up naturally on planet earth - if that is the argument. That some amino acids can be created in an environment that we now believe likely didn't exist, in a glass beaker that has now been shown to taint the results, doesn't even really point the way. If Miller did in fact "lead there" then we wouldn't now be looking at the vent possibility, panspermia possibility, and a host of other possibilities.

Panspermia is another possibility that has been proposed and it is plausible. But if Panspermia was the actual reason for life on Earth, then the question becomes where did the transplanted life come from?

For you.

Simple, as we have been told - women are from Venus, men are from Mars.

 

[devildavid]

For you.

No, in reality. It never happens. Not opinion, fact.

 

[Gordy327]

Simple, as we have been told - women are from Venus, men are from Mars.

[Slaps forehead] of course! It's also obvious now,

 

[Mulefoot]

No, in reality. It never happens. Not opinion, fact.

Again, for you. You don't get to decide for me the cause of physical phenomena.

Sorry.

 

[devildavid]

Again, for you. You don't get to decide for me the cause of physical phenomena.

Sorry.

No, in reality. Physical phenomena has physical causes. Every time. You or I don't have a say in this. There are not separate realities for everyone.

 

[Mulefoot]

No, in reality. Physical phenomena has physical causes. Every time. You or I don't have a say in this. There are not separate realities for everyone.

You also don't get to determine what constitutes the boundaries of reality.

 

[devildavid]

You also don't get to determine what constitutes the boundaries of reality.

That is correct. No one does. It is what it is.

 

[NWO_Spook]

They have, and they thought it was a dump. I simply went out to the toilet for a mere few seconds and they left me behind. Remember folks, always do a head count before leaving!

 

[LittleNipper]

My pastor does. Every Sunday he points skyward and says, "Put your faith and trust in JESUS! Do I have an amen?"

He is wrong.

 

[gboisjo]

The oldest forms of life on Earth are in the form of fossilized microorganisms discovered in hydrothermal vents that lived as early as 4.28 billion years ago.

Considering the Earth is 4.5 billion years old it speaks to the spontaneity of life.

Consider this, 4.28 Billion minus the 66 million since the extinction of dinosaurs its roughly 4.24 Billion.

4.24 billion years of evolution brought the Triassic, Jurassic, and Cretaceous Periods, what does that tell us about the trajectory of evolution.

Its not about brains, its about brawn. Life is plentiful in the Universe IMO, most of it not sophisticated, just life forms feeding on other life forms.

 

[gboisjo]

Panspermia is another possibility that has been proposed and it is plausible. But if Panspermia was the actual reason for life on Earth, then the question becomes where did the transplanted life come from?

Its not out of the question, Panspermia proposes that organisms such as bacteria, complete with their DNA, could be transported by means such as comets through space.

If its possible, where did it start, a hot water vent somewhere in our galaxy.

It sounds like, from this article, that the universe is predisposed towards evolving life, just not merging it on planetary scales.

There's a reason why aliens haven’t visited Earth yet, say scientists

The Fermi paradox questions why aliens have never visited Earth despite the Universe being so old and so vast that races should have evolved interstellar travel and come calling by now.

news.yahoo.com

According to a new hypothesis posed by Dr Wong and Dr Bartlett: “We propose a new resolution to the Fermi paradox: civilizations either collapse from burnout or redirect themselves to prioritizing homeostasis, a state where cosmic expansion is no longer a goal, making them difficult to detect remotely.

“Either outcome — homeostatic awakening or civilization collapse — would be consistent with the observed absence of (galactic-wide) civilizations.”

The pair argue that the general principles of life are universal and that although the emergence and evolution of life on other planets remains speculative, it may be inevitable.

Actually we have .

 

[grip]

I agree, we're lucky to be here ..but for a fluke 6 mile wide asteroid bumped out of the asteroid belt some 66 million years ago ..we wouldn't be here.

Life in general has its limitations and IMO the natural evolution of life isn't necessary directed towards smarts but more in the direction of dog eat dog survival.

The ability to adapt to environmental changes is key to survival. And humans happened to use their brains to adapt and survive, causing our intellect to far surpass our fellow animals. Most animals use mostly their instincts and usually find homeostasis within the ecosystem, while humans have become too successful and overrun our environment. Advanced lifeforms may be a fluke of nature, explaining our seeming rarity.

I know plenty of guys named Chip that they can have.

All true IMHO, but we would not even be here but for 7 mile wide fluke asteroid travailing at 45,000 mph, An impact equivalent to a billion nuclear bombs.

A few mammals survived in there burrows, that's it. Minus the asteroid the dinosaurs would have continued to evolve and mammals would have stayed small under the giants feet.

It begs the question, what is the thrust of evolution. And your right IMO, humanity has become a plague not compatible with the balance nature.

That is because there is factually no such thing as a balance of nature.

 

[gboisjo]

That is because there is factually no such thing as a balance of nature.

For 400 plus billion years there was an equilibrium as it relates to life in general.

First the asteroid and now us ..we humans are on a collision course to destroy our planet.

In the short span of a couple thousand years humanity has endangered the process in which life succeeds.

So, yes, in the end we will have disrupted the successful course of evolution.

The universe has as many stars as there are grains of sand on every beach on Earth. Try finding the one grain I marked as our sun if you dare.
