all that I am saying is if information and ideas are being covered that are mostly speculation why discriminate.
Because some speculative ideas lack any evidence. Otherwise, where should we stop?
We could spend the next 100 years teaching someone all the different unevidenced origins of life - 100 different aliens dropping seeds of life; 1000 different gods calling forth life; 10000 different wizards waving their wands. The number of "what if"s are almost endless. So, in science, we stick to things we have evidence of.
What makes any method more important to teach than the other?
Evidence. Always evidence.
May be it is personal belief but I honestly don't beleive that any speculation on how life began can be scientific.
Despite your beliefs, yes - it can be scientific. Experiments can be done; results can be measured; things can be learned.
How can an experiment be conducted when the variables are not even known.
But some variables are known. Ultimately, we may never find out the exact way that life originated on Earth, but we can investigate the different ways that life can originate.
