The main controversy is whewn stem cells are harvested from aborted fetuses, or when an egg is fertilized in a laboratory for the sole purpose of harvesting stem cells.
Stem cells can also be gotten from umbilical cord blood after a baby is born.

Ethical implications of embryonic stem cell research include concerns about the destruction of human embryos, potential misuse of the research for human cloning, and issues related to consent, privacy, and equity in access to treatments. It is important to balance the potential benefits of advancing medical knowledge and treatments with ethical considerations surrounding the value of human life and informed consent.
There might be ways to extract embryonic stem cells without damaging the embryo.

That might solve the problem of "killing" the embryo, but it would not solve the problem of "creating new life".
I don't know I think its with religion
The question is how the stem cells are obtained. When the stem cells are acquired from killing babies, many would object. Especially since stem cells can be obtained in other ways, and embryonic cells really offer no advantages.
The main ethical issue which has arisen with respect to the use of stem cells for medical purposes is that the best source of stem cells is the human embryo, but only if the embryo is aborted. The question then arises, was that embryo going to be aborted anyway, or was the decision to abort influenced by the need for stem cells. So then, we can argue that if an embryo was aborted specifically because of the wish to use its stem cells, it is not fair to kill that embryo, which otherwise could have become a human being. We might be in the position of killing one patient (if an embryo can be considered a patient) in order to save another, and that is not good ethics. There are, of course, also people who oppose abortion under any circumstances, whether stem cells are harvested or not, and these people will also have a problem with any use of embryonic stem cells, even when the abortion was going to happen anyway.
I think it is unethical to take from babies but it would be okay if you take from adults.
Stem cells do not have the conciousness to have ethical or moral issues.
People may hold them due mainly to their lack of knowledge over the functions of stem cells.

One argument against stem cell research is the ethical concern regarding the use of human embryos. Some individuals and groups believe that using embryonic stem cells involves the destruction of potential human life, which goes against their moral or religious beliefs.
Similarities: Both adult and embryonic stem cells have the potential to develop into different cell types in the body. They are both utilized in research to study cell behavior and potential therapies. Differences: Embryonic stem cells are derived from embryos, while adult stem cells are found in various tissues in the body. Adult stem cells have a more restricted potential to differentiate into specific cell types compared to embryonic stem cells. Ethical issues are often raised with the use of embryonic stem cells due to the source of their derivation.
embryonic stem cells can differentiate into more types of cells
One concern with stem cell research is the ethical issue surrounding the use of embryonic stem cells, as the extraction process involves the destruction of human embryos. This raises ethical questions about the beginning of human life and the rights of embryos.
