By only allowing one view on origins, we are basically killing any chance for our kids to discover critical thinking skills, rather than just following the imagination of another human being.

Falsified? that experiment produced all amino acids, basic building blocks of life, just from simple reducing atmosphere (similar to that of ancient Earth) and electricity (lightning). If anything it is a very good indication that theory of abiogenesis is indeed feasible.
Abiogenesis is far from disproven:

See, Thank you. Somebody who actually admits it. We need to do something to get this out of our science books.

There is nothing wrong with theaching alternative creation hypotheses alongside abiogenesis hypothesis. But not alongside evolution.

Abiogenesis assumes to explain creation through brute force. The problem is there is no instance where this has been observed. Panspermia is possible but at some point life has to be created. So, in my opinion, Occam's Razor is for a creator.

We should teach abiogenesis alongside other hypotheses like panspermia and supernatural creation as the possible origin of life - of course with the added clause that creation hypothesis is not scientific, since it assumes existence of the supernatural, which is against Occams Razor, in the absence of any other evidence for the supernatural.
Science must follow methodological naturalism, otherwise its not science:

I'm curious. What creation hypothesis is in high school science class?

What do you want to get out of science books? I dont understand. Both abiogenesis and creation hypothesis (along with panspermia and such) is already there.

Nope. The Amino Acids were racemized, which is absolutely useless for the creation of life, because right hand amino acids will kill a chain of left handed amino acids. Seriously, you should read into it. It's very interesting.
Models to explain homochirality
Some process in chemical evolution must account for the origin of homochirality, i.e. all building blocks in living organisms having the same "handedness" (amino acids being left-handed, nucleic acid sugars (ribose and deoxyribose) being right-handed, and chiral phosphoglycerides). Chiral molecules can be synthesized, but in the absence of a chiral source or a chiral catalyst, they are formed in a 50/50 mixture of both enantiomers. This is called a racemic mixture. Clark has suggested that homochirality may have started in space, as the studies of the amino acids on the Murchison meteorite showed L-alanine to be more than twice as frequent as its D form, and L-glutamic acid was more than 3 times prevalent than its D counterpart. It is suggested that polarised light has the power to destroy one enantiomer within the proto-planetary disk. Noyes[68] showed that beta decay caused the breakdown of D-leucine, in a racemic mixture, and that the presence of 14C, present in larger amounts in organic chemicals in the early Earth environment, could have been the cause. Robert M. Hazen reports upon experiments conducted in which various chiral crystal surfaces act as sites for possible concentration and assembly of chiral monomer units into macromolecules.[69] Once established, chirality would be selected for.[70] Work with organic compounds found on meteorites tends to suggest that chirality is a characteristic of abiogenic synthesis, as amino acids show a left-handed bias, whereas sugars show a predominantly right-handed bias.[71]
Occams Razor formulations:
Bertrand Russell offered what he called "a form of Occam's Razor" which was "Whenever possible, substitute constructions out of known entities for inferences to unknown entities."[5]
"entities must not be multiplied beyond necessity"
I'm curious. What creation hypothesis is in high school science class?

Are you serious? This is an experiment that falsified abiogenesis.

Please show one science textbook that teaches any of the hypothesis of abiogenesis as fact.
Why is abiogenesis even mentioned in school? Abiogenesis actually talks about life coming from non-life. The only thing we've observed is life coming from life, or biogenesis. My OP is basically stating; If we allow an imaginative idea about the origins of life to be taught in a science classroom, then what's the problem with teaching about other imaginitive ideas about the origins of life being taught in a science classroom.
Have you ever heard of the Miller-Urey experiment? Well, it can definitely answer how abiogenesis occurs; you should look into it.edit on 16-7-2011 by ledzeppelin489 because: (no reason given)

Abstract
The Darwin-Oparin-Haldane “warm little pond” scenario for biogenesis is examined by using information theory to calculate the probability that an informational biomolecule of reasonable biochemical specificity, long enough to provide a genome for the “protobiont”, could have appeared in 109 years in the primitive soup. Certain old untenable ideas have served only to confuse the solution of the problem. Negentropy is not a concept because entropy cannot be negative. The role that negentropy has played in previous discussions is replaced by “complexity” as defined in information theory. A satisfactory scenario for spontaneous biogenesis requires the generation of “complexity” not “order”. Previous calculations based on simple combinatorial analysis over estimate the number of sequences by a factor of 105. The number of cytochrome c sequences is about 3·8 × 1061. The probability of selecting one such sequence at random is about 2·1 ×10−65. The primitive milieu will contain a racemic mixture of the biological amino acids and also many analogues and non-biological amino acids. Taking into account only the effect of the racemic mixture the longest genome which could be expected with 95 % confidence in 109 years corresponds to only 49 amino acid residues. This is much too short to code a living system so evolution to higher forms could not get started. Geological evidence for the “warm little pond” is missing. It is concluded that belief in currently accepted scenarios of spontaneous biogenesis is based on faith, contrary to conventional wisdom.
