Because even back then they still knew enough about things to know that his theory was absurd.
Charles Darwin has not been discredited. He was and still is regarded as perhaps the greatest scientist that has ever lived.
There have been quite a few humans who tried to work out how organisms change with time. Lamarck tried his ideas but was discredited. Today's Theory of Evolution was discovered with evidence and thought by Charles Darwin and Alfred Russel Wallace. Darwin spent the most energy on gleaning evidence so the theory is these days credited to him. As David Attenborough says, he gave the idea 'irresistable force' when he happened upon a mechanism by which it could occur: Natural Selection.
Lamarck put two ideas into his theory of evolution thought to be true in his time.1. Use and disuse - people lose characteristics they don't use and keep the other ones .2. Individuals inherit the traits of their ancestors.So instead of the environment selecting traits, he said that the species selected the traits.Examples of what is traditionally called "Lamarckism" would include:1. Giraffes stretching their necks to reach leaves high in trees (especially Acacias), strengthen and gradually lengthen their necks. These giraffes have offspring with slightly longer necks (also known as "soft inheritance").2. A blacksmith, through his work, strengthens the muscles in his arms. His sons will have similar muscular development when they mature.
He proposed that the biological process of adaptive change over time was driven by an internal desire or motivation within the organism to achieve a goal, e.g., long necks in giraffes. He also incorporated the concept of group selection into his version of evolution, which was later discredited by Darwinism. Individuals always die faster than groups so natural selection will always operate on the individual before the group. Darwinism and current gene centred evolutionary theory has also demonstrated that adaptive change over time is driven by the environment and chance.
If dogs are bored, they may pass the time by eating poo. They also may be hungry, and cannot find anything else to eat. Some dogs just like to carry things in their mouth. If a dog is nervous, it may eat poo. There are many reasons why dog eat poo.
Darwin would not have known anything about genetics, which is why his theory was discredited initially, there was no mechanism for random mutation currently understood. On the other hand, the scientific evidence of the time supported Lamarck's theories, which with new understanding have been more or less discredited (ignoring neo-lamarckism and similar theories) which did not require any undiscovered mechanisms.
lamarckism
Lamarck's theory, known as Lamarckism, proposed that organisms could pass down acquired traits to their offspring. He suggested that an organism could change during its lifetime in response to its environment and these changes would be inherited by its offspring. However, this theory has been largely discredited in modern biology.
His argument was completely discredited.

Creationism should be chosen over those two any day.
Lamarck give the idea that an organism can pass on characteristics that it acquired during its lifetime to its offspring. Also known as heritability.
Snopes can be wrong sometimes and they will admit this and make corrections. The site as a whole will never be discredited due to this though.
