Life on other planets...

What do scientists deem to be "life" on other planets?

  • Does it use energy?
  • Does it reproduce?
  • Does it grow and develop?
  • Does it evolve over time?
  • Does it display organization?
  • Does it react to stimuli?
  • Does it maintain homeostasis?
  • Is it made of cells?*
If the answer is yes to all of those, then it is generally considered to be alive. Although, there is some grey area there as things like viruses do not reproduce on their own so there is debate on whether they are actually a living thing or not. Also, I imagine if a lifeform were found on another planet that had all the characteristics except for having cells, scientists would consider it a living thing.

Can it be aborted then or not?
 
There are more planets than all the grains of sand on all of the beaches in the world in our galaxy. There are millions and millions of other galaxies as well. Put those on millions of years of timeline, and it is highly likely that intelligent life exists or has existed elsewhere.

Energy is finite, it never goes away, just converts to another form, so the universe is always recreating itself. I believe in god for this reason. Not a dude in the sky, a massive knowing force in the universe.

How do those facts lead to the conclusion there must be a supernatural intelligence?

For me it is the realization that I can never fathom the size and complexity of the universe. As human beings e still do not under stand the complexities of our own bodies. Energy is very much an enigma, and it exists in many forms. I just choose to believe that I do not know, but it is likely their is a god.

You're pointing to a supernatural cause because there are complex systems and then going further to claim its the likely explanation based on an appeal to the state of ignorance in current human knowledge. That's no different than the ancients who created gods to explain lightning or why the sun moved. I don't see a link between complexity and the need for a god at all. Evidence of complex natural systems should simply lead you to believe nature is complex. Not that we need supernatural intelligence to arrive at a complex universe. That's quite an unsupported leap.

Hey, I will take the Faustian bargain, you can wrestle with your own implications if you are wrong.

I'm not sure this works either. That faustian bargain (which isn't really) only applies to the gods defined by certain religions. You already rejected their concepts too. So now you're in the position of defending a supernatural intelligence based on complexity while simultaneously eschewing complex thinking.

Stuff is complicated, therefor God.

The answer to "Life is too complex" is, when you take a million simple reactions and stack them on top of each other you get a very complex structure.

You guys kill clumps of cells every time you wash your hands. Murderers.

Was this supposed to be some kind of gotcha thread from 7 years ago?
 
Killing what?
You're a little slow, huh? It's not that hard to follow a thread that you're involved in. Let me simplify and see if you can figure it out...

Typically they get excited over a clump of cells
Welp, that just shows you're no scientist
Funny how that's considered life on every other planet or moon but Earth.
Is that your standard for not "killing" it?
Killing what?

Does that help?
 
100-200 billion galaxies at least in universe. Likely trillions of solar systems.

Guessing more than a few have planets roughly the same size as earth roughly the same distance from their star.

I would certainly bet their is life. can they travel many multiples faster than the speed of light to visit other life? Not sure I am willing to bet on that.
