Do you believe in life elsewhere?

It may help to take an elementary-level biology class before participating in discussions regarding aspects of biology. A reading comprehension course couldn't hurt, either, considering I never mentioned life coming from non-life, so that part of your post is a complete non-sequitur.
Oh boy, throwing punches already!

You didn’t give me the opportunity to tell you how I envy your intellectual capacity:D

More seriously, there is no need to turn the matter personal frankly, particularly over these questions…
 
I'm going to disagree with you on that one.

Life is nothing more than a (highly complex) form of ongoing chemical reaction. Just like a beautifully elaborate machine, the chemical pathways the cause X,Y,Z to happen are known and can be linked and modelled to show that X causes Y causes Z, (as a Biochemist working in a Biophysicists world).

Sadly you need to be specific when defining things in science, and with the majority of the life sciences community is down with life being an orchestra of chemical reactions.
Having a precise definition about a phenomenon though a necessary step in inquiry (scientific or not), doesn't mean that definition encompasses all there is to know about that particular reality. New findings may force a redefining of terms and a new consensus.

As you see (I think), science is dynamic not static!
 
Of course, science is open ended like that.

But to assume that what we currently know, is wrong, because there might be something more to it, isn't a sensible approach either. Science is very rarely completelly wrong (rarely, not never), and new findings tend to elaborate on previous ones, correcting by refinement as opposed to outright disproval.

I don't think there is anything more to life than a chemical reaction, there isn't any sort of mystic spark to it. Consciousness, on the other hand, is something I find quite interesting, defining the source of intellect is an interesting challenge.
 
I'm pretty sure there's some kind of an intelligent life form watching us right now and saying "hah, look at them..." just like we do when we watch apes.:smug:

The developmental distance between other great apes and humans is negligible in the grand scheme, human ego notwithstanding. Extraterrestrials which have advanced sufficiently to travel to Earth may not see us a much different than ants.

They are? I'm sorry but that's pure silliness. Given the vast pool of both skilled and expendable labor available to the pharoahs it was certainly within their power to build the pyramids. Men had been constructing buildings and towns and monuments for a thousand years prior to the pyramids. They were simply large construction projects.

No one yet has explained how they moved blocks of stone that large up and into place, no theory yet builds them with the technology they possessed. Earth ramp? Nope, serpentine ramp? How to make the turns in a diminishing radius? Find the explanation that works with the tech they had...
 
No idea for life elsewhere
but there are damn well documented ways to built pyramid once you get the wheel and pulley down without invoking outside technology. Egyptians did have a rather long low season in agriculture, working on pavement for the Man in exchange of something to eat just made sense.

I wasn't making the matter personal, nor was I trying to insult you, nor was I trying to claim superiority in any way. I was serious; if you want to discuss life, then you should educate yourself on what scientists consider life to be. It's quite simple.

Yes, but they didn't have the pulley. Ramp & rollers were the extent of their machines.
 
Microscopic or even planetary life? I think so. Humanoid life? The older I get the less I believe it. Seems like we would have noticed something by now...radio signals or something. UFOs don't count IMO. If such life forms exist throughout the universe, seems like there would have to be some that are really advanced and would transmit their existence to the corners of the universe. To me it's kind like the question of whether someone would invent a time machine in the future. If such a machine exists in the future, why hasn't anyone come back to our time?

The nearest star to the Sun is Alpha Centauri, which is just under 4.5 light years away. It took the Earth roughly 4.5 billion years to have a species that could create things like radio waves. Taking that into consideration, these radio waves have only been emanating from the Earth for the last 100 years or so. Beyond that, we've only been sending out signals that might have the strength to get past our solar system and solar winds and other radiation for maybe the last few years, if that.

Add to all that that our ability to detect signals from other planets that would probably be just as faint, if not more so, have only been around for a matter of decades, maybe, and I'm not at all surprised we haven't found other forms of life, especially when the only planets we've identified as being like Earth, that exist in that "comfort zone" are very far away and we don't know to look for any type of life other than what we know here on earth (which now includes arsenic as a potential fundamental element, which is way cool).
