UFO's- Please help me process

Sorry, I meant on Earth.

Highly likely but there won't be any traces left.

If you look at it in detail at the very basis of all biological replication is RNA.
RNA though while very good at producing copies of itself is also quite instable and breaks down easily.
Traces only persist since RNA accidentally managed to produce DNA analogues and those stumbled across a recipe to create cell walls around themselves which further protect it.

RNA and DNA are naturally occurring and the primary carriers of genetic information. Now add in some amino acids and you have everything needed for life.

I think it was in the 60s when somebody recreated the conditions of early Earth in a glass bottle. To his surprise within two weeks complex amino acids had formed which when produced with an aim to create some specific ones on purpose was quite difficult but once you extrapolate from a single small bottle and 14 days to the entire planet and say a few million years it is practically inevitable that the ones necessary for life as we know are amongst them in abundance.
The first one managing to build a cell wall to protect itself would very quickly outcompete the others and swiftly take over.


But then of course you have the problem of getting from single cells to multicellular life and that is a really bottleneck because somehow the individual cells need to be stopped from acting in their own 'self-interest' ie under certain circumstances to commit suicide for the multicellular life form to survive rather than just replicate which comes naturally to them.
Cancer is an excellent example for what happens if these controls break down, a cell does not destroy itself and reverts to type.

Which is why I think that if we ever were to find life on another planet it is most likely going to nothing more than single cell organisms.
 
This is Captain Obvious commenting about the huge distances involved between different solar systems with planets. The nearest star is Alpha Centauri, if I remember well, and this is FOUR LIGHTYEARS away! Since, a lightyear is quite a little more than a mile, it seems it is logically impossible to travel such distances. This limitation also applies to space probes. To complicate matters even more, the undisputedly unique genius of Albert Einstein, predicted that the speed of light is the ultimate winner of all speed records. No one can ever travel faster than that, as travelling at the speed of light would amount to a non-zero mass to possess an INFINITE amount of kinetic energy, and this energy has to be produced by engines with a finite power and a nice collection of engineering challenges/problems.

We can dream of ever succeeding to penetrate deep space, but this, will "happen" when not even the dust of my bones will exist.

A valid perspective, yes. Whether or not that proves to be the correct perspective remains to be seen. We don't yet know which perspective is correct simply because we don't yet have the technical capability to find out. Therefore, in the meanwhile, it is human arrogance and vanity to deny the possibility of life elsewhere, and quite possibly on a nearby planet. :scratch2:
Actually, we do have the capability...to rule it out. And if there is we will forever remain isolated and never confirm it since as time passes the impossibility continues to increase exponentially. We have the knowledge to arrive at this inevitable conclusion.



I am by no means a crusader in this regard. All we have to do is the math.
 
Why are there so many different UFOs? You think there are dozens of different alien races visiting us right now. Space and time are too large.

Perhaps, there are. Didn't an outgoing Israeli defense chief recently say that there is something akin to a Federation of Planets (yes, like in Star Trek), and that aliens from there were very concerned that humanity was not prepared for disclosure and would panic? Which, I also suspect would happen.

The weirdest reports seem to be the ones not involving what we would recognize as a vehicle. It's reports such as the 1980 Rendlesham Forest incident in the U.K., where there were traditional UFO vehicles, and also what was described as phenomena appearing like an glowing red/orange object resembling an eye, hovering just above the forest floor. Dripping of what appeared to be molten steel - probably said for lack of better descriptors. More recently, one the Navy sightings was described as a transparent sphere, a meter or two in diameter, with a cube inside it like some flying beachball, just tooling around the sky and toying with the Navy jets. Zooming past them within a few meters, at high velocity. No sign of occupants, flight surfaces, propulsion, or any other machinery as we know it. Bizarre, doesn't begin to describe either of these incidents.
