One of the most widespread doctrines of Christian Gnostics is that the angry and jealous God of the Old Testament could not possibly be the loving God of the New Testament. From this developed a range of doctrines about just how the world was created, with two Gods and also Sophia (Lady Wisdom - see the Book of Proverbs and a whole range of 'Wisdom literature').
Christian Gnostics were strongly vegetarian. They believed that 'light' existed in vegetables, but particularly in melons, so consumption of melons was encouraged. Many Gnostic denominations believed that the world is impure or evil and that for this reason sex should not be performed when there was any chance of bringing an innocent child into the world.
Gnosticism can be read about in many books. The Gnostic Society has their own Library in which everything about the Gnosticism can be learned or studied.
there is no scientific basis for Gnosticism or orthodox (mainstream) Christianity.
The opponents of Gnosticism were primarily early Christian leaders and theologians, such as Irenaeus and Tertullian. They argued against Gnosticism's belief in secret knowledge and its rejection of the material world, emphasizing instead the importance of orthodox Christian doctrine and the belief in a loving creator God.

Simon Magus
Gnosticism does not have a single founder as it emerged from diverse religious and philosophical influences in the ancient world. However, it is believed to have been shaped by various early Christian and Jewish sects, as well as elements of Hellenistic and Persian mysticism.
Pneuma
No book in the bible addresses Gnosticism, you are looking for Against Heresies as written by a father of the church, Irenaeus.
Business premises is correct, just as you have it.
