The theory of evolution hypothesizes that single-celled plant-like creatures, whose origins it is unable to explain, came in time to form algae. The origin of algae goes back to very remote times. So much so, that fossil algae remains from 3.1 to 3.4 million years old have been found. The interesting thing is that there is no structural difference between these extraordinarily ancient living things and specimens living in our own time. An article published in Science News says:
The German biologist Hoimar von Ditfurth makes this comment on the complex structure of so-called "primitive" algae:
The oldest fossils so far discovered are objects fossilized in minerals which belong to blue green algae, more than 3 billion years old. No matter how primitive they are, they still represent rather complicated and expertly organized forms of life.342
Evolutionary biologists consider that the algae in question gave rise over time to other marine plants and moved to the land some 450 million years ago. However, just like the scenario of animals moving from water onto the land, the idea that plants moved from water to the land is another fantasy. Both scenarios are invalid and inconsistent. Evolutionist sources usually try to gloss over the subject with such fantastical and unscientific comments as "algae in some way moved onto the land and adapted to it." But there are a large number of obstacles that make this transition quite impossible. Let us have a short look at the most important of them.
1- The danger of drying out: For a plant which lives in water to be able to live on land, its surface has first of all to be protected from water loss. Otherwise the plant will dry out. Land plants are provided with special systems to prevent this from happening. There are very important details in these systems. For example, this protection must happen in such a way that important gases such as oxygen and carbon dioxide are able to leave and enter the plant freely. At the same time, it is important that evaporation be prevented. If a plant does not possess such a system, it cannot wait millions of years to develop one. In such a situation, the plant will soon dry up and die.
2- Feeding: Marine plants take the water and minerals they need directly from the water they are in. For this reason, any algae which tried to live on land would have a food problem. They could not live without resolving it.
3- Reproduction: Algae, with their short life span, have no chance of reproducing on land, because, as in all their functions, algae also use water to disperse their reproductive cells. In order to be able to reproduce on land, they would need to possess multicellular reproductive cells like those of land plants, which are covered by a protective layer of cells. Lacking these, any algae which found themselves on land would be unable to protect their reproductive cells from danger.
4- Protection from oxygen: Any algae which arrived on land would have taken in oxygen in a decomposed form up until that point. According to the evolutionists' scenario, now they would have to take in oxygen in a form they had never encountered before, in other words, directly from the atmosphere. As we know, under normal conditions the oxygen in the atmosphere has a poisoning effect on organic substances. Living things which live on land possess systems which stop them being harmed by it. But algae are marine plants, which means they do not possess the enzymes to protect them from the harmful effects of oxygen. So, as soon as they arrived on land, it would be impossible for them to avoid these effects. Neither is there any question of their waiting for such a system to develop, because they could not survive on land long enough for that to happen.
There is yet another reason why the claim that algae moved from the ocean to the land inconsistent-namely, the absence of a natural agent to make such a transition necessary. Let us imagine the natural environment of algae 450 million years ago. The waters of the sea offer them an ideal environment. For instance, the water isolates and protects them from extreme heat, and offers them all kinds of minerals they need. And, at the same time, they can absorb the sunlight by means of photosynthesis and make their own carbohydrates (sugar and starch) by carbon dioxide, which dissolves in the water. For this reason, there is nothing the algae lack in the ocean, and therefore no reason for them to move to the land, where there is no "selective advantage" for them, as the evolutionists put it.
All of this shows that the evolutionist hypothesis that algae emerged onto the land and formed land plants is completely unscientific.
