The argument you're referring to is often presented as the cosmological argument, which is a philosophical and theological argument used to support the existence of a deity or a first cause. While different versions of the cosmological argument exist, they generally emphasize the idea that everything that begins to exist must have a cause.
The claim that "something cannot come from nothing" is often put forward by theists as a way to challenge the possibility of an uncaused universe. The argument suggests that if the universe had a beginning, there must have been a cause or explanation for its existence.
However, it's worth noting that when theists argue for the existence of God as the creator of the universe, they typically posit that God is a necessary and uncaused being. In this perspective, God is seen as existing eternally and independently, not dependent on any external cause or explanation.
So, in the context of the cosmological argument, theists are not claiming that the universe emerged from absolute nothingness. Instead, they argue that there must be a transcendent cause or explanation for the existence of the universe, which they identify as God.
It's important to recognize that philosophical arguments like the cosmological argument are complex and subject to debate. Different philosophers and theologians may present and interpret these arguments in various ways, leading to diverse perspectives and conclusions. It is not uncommon for different individuals to hold different views and interpretations of these arguments, even within the broader theistic community.
