Please demonstrate how you avoid this.
I don't have to avoid anything. I only have to follow the science. Where there is no evidence, I say I don't know.
Science says life always comes from life. Science currently has no clue how life started in the universe. But so what? Science at one time didn't know what caused the common cold. That didn't hamper the fact that science knew colds were infectious.
I keep telling you what science says and you keep asking me to guess on things science does not yet know. What science does not know does not disallow what science does know.
What is the starting point of this 2000 years?
On Earth Ludo, on Earth.
You aren't making guesses because you know your guess is a contradiction in terms:
No. I'm not making guesses because guessing is not science.
If at point A, there was no life, and at point C there is life, then life came about abiogenetically by definition.
That is a logical fallacy. If at point A, there was no life, and at point C there is life, then EITHER life came about in a way we don't yet know, or your premise is incorrect.
You're saying it didn't because we've never seen it happen, I get that. But I'm saying what then is your alternative: life only comes from life? If so, where'd that life come from?
We don't currently know! What? You reject science not knowing everything?
But in not knowing, why in the world would we substitute a theory with no evidence, that never been known to occur, and goes against what we have observed since we've been keeping records? Why?
Because there is no alternative you say. But assuming because science doesn't know is NOT science! It's superstition.
And worse, you are assuming something that has not one scrap of scientific evidence for it! None.
Yes, we've found 4000 planets. In the last forty years! And you apparently believe all of these planets have been thoroughly explored.
You aren't thinking.
Given the time scales of your theory..
1. The universe should be infested with life, it should be everywhere.
2. Some of that life should have by now, like us, attained advanced technology. We (and they ) should by now have picked up radio frequency radiation.
3. Some of that life should have already reached very advanced technology and should have discovered us already.
4. No life being found in the universe so far, no life in the solar system, no life on Earth, is evidence that supports life only from life, and life never from abiogenesis.
Let me ask you some questions.
How did water get on Earth? Do you know that the Earth is unique not only in having life, but in having water?
The theory was that water was brought to Earth by comets. Why did those comets miss all the other planets?
Now a developing theory says the Earth always had water. Scientists are finding out that the water on the Earth is as old as the sun.
Are we to think that water spontaneously generated on Earth because no alternative theory exists? Or because oxygen and hydrogen existed so....water?
Science currently says that the earth was at one time too hot to have water. Yet water is here now. Plenty of it.
If at point A, there was no water, and at point C there is water, then water came about spontaneously by definition.
Is this logical?
