StarshiptoMarsSimulation.swapBack() (#1141-1175) sends eth to arbitrary user
Dangerous calls:
- (success,None) = address(marketingAddress).call{value: bnbForMarketing}() (#1166)
StarshiptoMarsSimulation.addLiquidity(uint256,uint256) (#1200-1210) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,liquidityAddress,block.timestamp) (#1202-1209)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

Don't use strict equality to determine if an account has enough Ether or tokens.

Combination 1: Reentrancy vulnerabilities + Functions that send Ether to arbitraty destination. Usual for scams. May be justified by some complex mechanics (e.g. rebase, reflections). DYOR & manual audit are advised.

Pragma version0.8.9 (#11) necessitates a version too recent to be trusted. Consider deploying with 0.6.12/0.7.6/0.8.7
solc-0.8.9 is not recommended for deployment
Deploy with any of the following Solidity versions: 0.5.16 - 0.5.17, 0.6.11 - 0.6.12, 0.7.5 - 0.7.6 Use a simple pragma version that allows any of these versions. Consider using the latest version of Solidity for testing.

Low level call in StarshiptoMarsSimulation.swapBack() (#1141-1175):
- (success) = address(teamAddress).call{value: bnbForTeam}() (#1165)
- (success,None) = address(marketingAddress).call{value: bnbForMarketing}() (#1166)
- (success,None) = address(marketingAddress).call{value: address(this).balance}() (#1173)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence
