Brain development in early childhood is of critical importance in the lifelong education process due to the high number of neurons and the high potential to form interneuron connections. The human brain, which has never been so active and productive in any period of life, makes it meaningful and necessary to benefit from this natural equipment with an educational view. In the early childhood period, when the foundations of religious education are laid, it is necessary to prepare the education program (...) by taking into account the child’s neural development and selecting teaching materials and methods that will appeal to children’s senses. In this case, attention is drawn to the importance of educational activities that enable the child to gain a large number of experiences. Early childhood religious education is designed in a way that gives the child multiple experiences in line with the data of educational sciences. It is believed that the richness of stimuli offered to the child in this period contributes to her/his cognitive, emotional and psychomotor development. However, the contribution of the richness of stimuli in early childhood religious education to the cognitive development of the child is not sufficiently discussed in terms of its suitability for brain development or neural structure. For this reason, the aim of our study is to establish the neuroscientific basis of the richness of stimuli that should be presented in accordance with the child's brain development in early childhood religious education. Early childhood religious education should be designed in a way that allows the child to have different experiences, based on the fact that religious development is not independent of other developmental areas. The tendency to believe in God in the child's nature proves the religious education that should be given in the first years of life. The child is innately ready to understand and accept religion and has an interest and inclination to believe in Allah. Therefore, religion should be one of the matters of the child's life from an early age, and religious content should be included in educational activities. During this period, the number of neurons in the child's brain and the potential to form synaptic connections between neurons is quite high. In order to benefit from this neural capacity at the highest level, the child needs a learning environment equipped with rich stimulus. The adaptability and flexibility of the brain to new learning, which is expressed by the concept of neuroplasticity, reaches its highest level in early childhood. Since neuroplasticity occurs mostly in areas of the brain related to vision, hearing, motor and language skills, it has been revealed that stimuli that activates these regions of the brain in early childhood religious education support its synaptic bond development. Firstly, it is possible to use music as a means of entertainment and learning in early childhood religious education because early children enjoy singing songs as well as hymns and poems. The melodic presentation of the text facilitates the memorization of suras and praying and makes it funny. The educational aims achieved by enjoyable activities enable the brain to form bonds that associate these actions with entertainment. Secondly, synapse formation is quite high when exposed to visual stimuli in the early childhood period. For this reason, it is necessary to enrich the visualization for early childhood. Consequently, the more visual stimuli are included in religious education, the more synapse formation will increase. Thirdly, motor activities positively affect neuroplasticity, creating new connections between neurons which can even be used for cognitive activities. Finally, religious curiosity in early childhood guides adults about the content and timing of religious stimuli to be presented in this period. With the religious curiosity that appears from the age of 3-4, children ask questions about religious concepts and show interest in religious activities. Therefore, every new information presented to the child's curiosity ensures the formation of new synapses in his/her brain. As a result of the research, the activities such as stories/parables, drama/games, songs/rhythms, physical activities, nature trips, visits to religious places, etc., in early religious education contribute to the brain development of early children. It has been revealed that the activities provide the opportunity for effective and permanent learning by supporting the neural development of the child. It is recommended to carry out more comprehensive studies in which the neuron activity in the early child's brain can be observed during religious learning with the help of magnetic brain imaging devices in the discipline of religious education.
