I need help to solve this problem. Tell me which programming language I should use for creating a web-based, interactive educational platform that has customizable options and can be used on both Windows and Linux platforms? The software must have the ability to create virtual environments simulating ecosystems of different planets. Additionally, include details about how it would implement the "Learning Pathway" concept in its design, ensure compatibility with the UN Framework 4x867 architecture, support AI-based adaptive learning algorithms, and allow for securely storing student data using a combination of SQL databases and encryption techniques to protect sensitive information. The platform should also include multi-lingual support to make it user friendly worldwide. Provide me with the complete software requirements list required to build such a system from scratch without any explanations.
